I can confirm that this builds fine with JDK 14.0.2, and I've uploaded the bits for testing. https://oss.sonatype.org/content/repositories/comdukescript-1139/com/dukescript/nbjavac/nb-javac/ |

The build works fine with JDK 14.0.2, and the staged bits are available here: |

this is pretty cool. How comes that this didn't make it in yet? |
|
@JaroslavTulach : does this also work with JDK 17 or only JDK 14 ? |

The nb-javac overview proposal suggests to minimize differences between JDK's
javacandnb-javacby automatically applying advanced refactorings and thus making sure thejavacfrom recent JDK can run on JDK8. This PR is implementation of that idea.The best part of this PR is the deletion of more than
230 000lines of code, that are no longer needed to be maintained. Rather than that the build script starts by checking out a JDK repository (currently at revisionJDK-16+36). Thesrc/java.compilerandsrc.jdk.compilersources are then massaged to use only JDK8 APIs using advanced refactorings transformations. As a result of that thenb-javacsources can link against JDK8+ APIs.The next step is to take the code and compile the source to JDK8's bytecode. Once finished, the outcome remains the same: two JAR files in the
make/langtools/netbeans/nb-javac/dist/folder. Those can be used and tested with any JDK8+.
