eclipse tycho + java 11 = Unknown OSGi execution environment: 'JavaSE-11'

How to build an eclipse RCP app based on Java 11 with tycho?
I'm using eclipse 2018-09 RCP + the Java 11 plugin + OpenJDK 11
My application is plugin-based and in all the plugins, theMANIFEST.MFfile contains:

Bundle-RequiredExecutionEnvironment: JavaSE-11

The tycho build fails with the following exception:

    [ERROR] Internal error: org.eclipse.tycho.core.osgitools.OsgiManifestParserException: Exception parsing OSGi MANIFEST {...}\META-INF\MANIFEST.MF: Unknown OSGi execution environment: 'JavaSE-11' -> [Help 1]
    org.apache.maven.InternalErrorException: Internal error: org.eclipse.tycho.core.osgitools.OsgiManifestParserException: Exception parsing OSGi MANIFEST {...}\META-INF\MANIFEST.MF: Unknown OSGi execution environment: 'JavaSE-11'

Is tycho compatible with Java 11? if so how to configure it to build java 11 RCP apps?

I found this post that is very similar (for Java 10...)

Solution

  • Using eclipse RCP v2018-12 (v4.10) + eclipse tycho v1.3.0 solved all my problems
    JMSToolBox is now developped and distributed with Java 11
