openapi-generator version

Versions 3.3.1 through 3.3.4 result in the same error. Version 3.3.0 works.

Command line used for generation

gradlew --stacktrace --debug

Steps to reproduce

Empty Android Studio 3.2.1 project + Gradle 4.10, only add openapi-generator-gradle-plugin to the classpath

build.gradle:

buildscript {
    
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'org.openapitools:openapi-generator-gradle-plugin:3.3.4'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Thanks for reporting it. I'll take a look. I've run the generator on Gradle 4.10.2 since the linked fix
for 4.10 support (which was published in 3.3.0), so I'll have to keep looking.

The only two other changes since 3.3.0 are:

• Replacing System properties for GeneratorProperties (98ae7a8#diff-2e87581015053cfbb5d5d06f97214a15)
• And JDK 9 support (56c4751#diff-2e87581015053cfbb5d5d06f97214a15 and 12a702e#diff-2e87581015053cfbb5d5d06f97214a15)

[jimschubert]

@jacobblock I'm unable to reproduce the error you're seeing. I've tried this on a freshly downloaded Android Studio 3.2.1, where I've created a mostly default Android app for phones & tables (with and without the automatically generated Activities). I've then followed these steps each time to evaluate:

• gradle -v => 4.10.2
• gradle build => success
• ./gradlew -v => 4.6 (this is the default version in the new Android Studio)
• Build in Android Studio with Make Project toolbar button
• Add apply plugin: 'org.openapi.generator' to build.gradle (this is missing your your build.gradle, and without this the openapi-generator plugin doesn't run any code at build time
• Rebuild in above ways => all success
• Add an openApiGenerate task (see below), and execute that task in above variants (4.10.2, 4.6, IDE - - task is under the openapi tools grouping) => all success

When I run the builds, I do see lint warnings:

> Task :app:lint
Ran lint on variant release: 2 issues found
Ran lint on variant debug: 2 issues found
Wrote HTML report to file:///Users/jim/AndroidStudioProjects/MyApplication2/app/build/reports/lint-results.html
Wrote XML report to file:///Users/jim/AndroidStudioProjects/MyApplication2/app/build/reports/lint-results.xml

To investigate further, I'd need some repro steps and further details. For instance:

• when you said you use Gradle 4.10.2… did you manually change the gradle wrapper?
• Can you check your gradle configuration in the IDE and verify that you're using the gradle wrapper and not and older system Gradle? I changed my IDE settings to use the wrapper and the system 4.10.2 installed version of Gradle, but all built successfully:
  .

A point of note is that the build.gradle script you've shared above would be your project-level script (such as MyApplication) while the error in your issue describes an error in the other module (:app). Gradle throws this error when that module's script can't be run correctly (see DefaultScriptRunnerFactory.java#L92)

The full stacktrace you've provided suggests this comes from a different plugin:

15:22:17.058 [ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter] Caused by: java.lang.NoSuchFieldError: ASCII
15:22:17.058 [ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter] at com.android.build.gradle.BasePlugin.checkPathForErrors(BasePlugin.java:1006)

This error suggests it is calling checkPathForErrors, and then is not able to find the field ASCII in CharMatcher.ASCII.

CharMatcher comes from Guava, so it's possible that you have some dependency pulling in an outdated or incompatible version of Gauava. Following that bit of code, it links to http://b.android.com/95744 for details. However, the path at the bottom of your stack trace looks valid to me.

To skip this error, you could try setting the SKIP_PATH_CHECK_PROPERTY which skips the block of code from above which would attempt to read the missing CharMatcher.ASCII by adding this to your gradle.properties:

com.android.build.gradle.overridePathCheck=true

Or, you could add Guava to the classpath and force a specific version. I did find that openapi-generator is using 26.0-jre of Guava, for which the android packaged CharMatcher is Ascii rather than ASCII (see CharMatcher). Although it doesn't look like that type has changed for some time, and I'd find it hard to believe that Android or the Android Gradle Plugin is years out of data for Guava. I'd have to pull the Android source code (which takes an hour or more) to dig any further.

[jimschubert]

@wing328 do you have access to Windows and Android Studio to see if this is OS-specific?

The only thing I've seen referenced in Android for Guava is 0.15, and it doesn't seem like a good idea for us to downgrade 0.26 to 0.15. If anyone is familiar with the Android toolchain, please correct me if I'm wrong.

[jacobblock]

@jimschubert thanks for the investigation. To answer your two questions:

when you said you use Gradle 4.10.2… did you manually change the gradle wrapper?

Yes this was the only change.

Can you check your gradle configuration in the IDE and verify that you're using the gradle wrapper and not and older system Gradle?

Yes I receive the same error running gradlew in terminal, with correct gradle version displayed.

My app build.gradle is default empty android app:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.jblock.myapplication"
        minSdkVersion 28
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

I saw what you mentioned in the stack trace, that the error comes from com.android.application, but it was not clear to me the interaction. Incompatible libs is a possibility, I will look into that further. Setting com.android.build.gradle.overridePathCheck=true in my root gradle.properties unfortunately has the same error.

Add apply plugin: 'org.openapi.generator' to build.gradle (this is missing your your build.gradle, and without this the openapi-generator plugin doesn't run any code at build time

Yes I am running the 3.3.0 generator fine in another project; I was just able to reproduce my error with the newer versions with a limited android project during configuration step.

[jimschubert]

Sorry for taking so long to respond back. I've had to renew my Parallels Desktop subscription and make some drive space in order to install Android Studio in my Windows VM.

I was able to get this working. I'm not sure if this is considered a hack or not, and it is a mixture of solutions I found in the following pages:

• https://developer.android.com/studio/known-issues
• https://issuetracker.google.com/issues/38419426#comment8
• https://issues.jenkins-ci.org/browse/JENKINS-23794
• Guava-dependency conflicts with android gradle plugin 0.14.0 jfrog/build-info#39

The problem is that the Android Gradle Plugin uses an incompatible version of Guava. I attempted to revert the version back to 20.0 (introduced via e85c527), but doing so made tests hang on my machine. I also attempted to revert the the mockito version change from that commit, and rather than hanging the tests would fail abruptly and exit Maven. I assume that bumping these versions were related to the maven plugin version bump, and I'm not sure where to look for conflicts.

Rather than revert our versions in order to be compatible with Android, I tried a few variations of the fixes I found above (including forcing guava 15.0).

The configuration I've found that works is:

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath('org.openapitools:openapi-generator-gradle-plugin:3.3.4') {
            exclude group: 'com.google.guava'
        }
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

configurations {
    compile.exclude module: 'guava-jdk5'
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Notice the guava exclude on our gradle plugin as well as the compile.exclude module: 'guava-jdk5' line.

I usually don't like being so heavy-handed with dependencies for fear that something won't work as expected. However, I added the generation samples from the gradle plugin and pointed them to a valid hosted spec, and all tasks completed as expected (append this to the above build.gradle to test it out):

apply plugin: 'org.openapi.generator'

openApiMeta {
    generatorName = "Sample"
    packageName = "org.openapitools.example"
    outputFolder = "$buildDir/meta".toString()
}

openApiValidate {
    inputSpec = "https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator-gradle-plugin/samples/local-spec/petstore-v3.0.yaml"
}

// Builds a Kotlin client by default.
openApiGenerate {
    generatorName = "kotlin"
    inputSpec = "https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator-gradle-plugin/samples/local-spec/petstore-v3.0.yaml"
    outputDir = "$buildDir/kotlin".toString()
    apiPackage = "org.openapitools.example.api"
    invokerPackage = "org.openapitools.example.invoker"
    modelPackage = "org.openapitools.example.model"
    configOptions = [
            dateLibrary: "java8"
    ]
    systemProperties = [
            modelDocs: "false"
    ]
}

task buildGoSdk(type: org.openapitools.generator.gradle.plugin.tasks.GenerateTask){
    generatorName = "go"
    inputSpec = "https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator-gradle-plugin/samples/local-spec/petstore-v3.0.yaml"
    additionalProperties = [
            packageName: "petstore"
    ]
    outputDir = "$buildDir/go".toString()
    configOptions = [
            dateLibrary: "threetenp"
    ]
}

task generateGoWithInvalidSpec(type: org.openapitools.generator.gradle.plugin.tasks.GenerateTask){
    validateSpec = true
    generatorName = "go"
    inputSpec = "https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator-gradle-plugin/samples/local-spec/petstore-v3.0.yaml"
    additionalProperties = [
            packageName: "petstore"
    ]
    outputDir = "$buildDir/go".toString()
    configOptions = [
            dateLibrary: "threetenp"
    ]
}

I'm hesitant to document this in the gradle plugin's README because it seems like a hack more than a fix, but in researching it this seems to be a common problem with the Android Gradle Plugin.

[jimschubert]

I should also comment that this behavior is only present on Windows. Adding the openapi-generator-gradle-plugin in Mac works as expected without any conflict in the Android Gradle Plugin.

@wing328 what are your thoughts about documenting this?

[wing328]

what are your thoughts about documenting this?

I think we should document the workaround in case someone is looking for one. I've labeled this issue with "Issue: Workaround available" for the time being.

[jimschubert]

@wing328 Thanks. I think we can document on the README, then just refer users to the README from other relevant doc locations. My concern was that it was a hack and that some generators might not work, but we can just add a caveat.
