Forces me to use a license field

[rix0rrr]

I don't want to license my package, however jsii forces me to or it will not build:

Error: /home/local/ANT/huijbers/Workspaces/CDKAnalytics/src/CDKAmznResources/packages/cdk-amzn-resources/package.json has "license" UNLICENSED, which doesn't appear to be a valid SPDX identifier

• unlicensed or UNLICENSED are not accepted
• The package is marked private: true so I think jsii has no business checking my license at all.

LicenseRef-LICENSE is also not accepted.

I seem to be forced to license my code under some Open Source license

Proprietary is also not accepted.

Is this code not wrong?

https://github.com/awslabs/jsii/blob/master/packages/jsii/lib/package-metadata.ts#L5

Should that not have been use of this package? https://www.npmjs.com/package/spdx-expression-validate

UNLICENSED is accepted by the rewrite I have in #188.

It was an oversight in the current version. But yes, SPDX license identifier or UNLICENSED is all that is valid

[RomainMuller]

Resolving. UNLICENSED is now an option.

How can we add custom licenses? We have a custom propietary license which must be used to be compliant.
This is in the format LincenseRef-XXX, but is rejected by jsii.
