[ERROR] Exception in thread "main" com.sun.tools.javac.util.Abort

I am getting this error while trying to convert my code using the j2objc maven plugin:

Up until recently the conversion ran without issues on all of my projects using the same config. I suspect that auto updating JDK / Maven versions might be the root cause, but I still face this when changing to older versions of both.

Any idea what could be causing this? I'm also unsure of how to get further logs / error info.

This is my plugin configuration:
<plugin> <groupId>com.smoope.utils</groupId> <artifactId>j2objc-maven-plugin</artifactId> <version>1.1.4</version> <configuration> <skipParent>true</skipParent> <failOnErrors>true</failOnErrors> <j2objcPath>/Users/j2objc-2.8/j2objc</j2objcPath> <d>${project.build.directory}/j2objc/src</d> <sourcePath>${project.basedir}/src/main/java</sourcePath> <encoding>CP1252</encoding> <useArc>true</useArc> </configuration> </plugin>

Hi @kpit-vchck , did you check that downgraded JDK is indeed used within the project? I can't really say why it happens, but stacktrace points to javac which is JDK-related thing. I also found something similar here: google/j2objc#1034 where they also suggest to upgrade the lib itself. So maybe try to play with different. j2obc and java versions
