BUILD FAILED
/home/nntin/git/javaforce-30.0/build.xml:45: Compile failed; see the compiler error output for details.

error: package com.sun.source.tree does not exist could be fixed with cp /usr/lib/jvm/java-8-openjdk-amd64/lib/tools.jar javaforce/jars/. ElementScanner9 is from the Oracle JDK. Please also support OpenJDK due to licensing.

pquiring commented 3 years ago

JavaForce usually requires the latest JDK - Current JDK15 is required for many features. Can you upgrade your JDK?

NNTin commented 3 years ago

That worked. Thank you! Is my understanding correct that even if I build it with OpenJDK 15 I can still use OpenJDK 8 to use the built javaforce.jar? My main project is using OpenJDK 8 and won't upgrade.

pquiring commented 3 years ago

Possibly, it depends on what methods are called. Most JARs are built with source level 8 (1.8 actually) so they should run under JDK8 unless they use methods that are not available in JDK8.

pquiring commented 3 years ago

If you using Linux such as Debian, they are finally releasing newer versions of Java in Debian 11 which is due out next year. I would just download and manually install newer versions of Java if possible.

Thank you!
