Ok sorry for the spam but I found that it is not a too long classpath issue.
One jar in the classpath is causing a strange error [ERROR] error: illegal argument for --class-path: Illegal char <:> at index 54: C:/Users/Greg/.m2/repository/jhealpix/jhealpix/3.2.0/.:lib I don't know what's wrong with this guy, it is available in the repo and the classpath displayed in the error message is not the actual path file in the generated option file: C:/Users/Greg/.m2/repository/jhealpix/jhealpix/3.2.0/jhealpix-3.2.0.jar There is something really strange happening here , maybe some conflicting jar libs ? ... Good news is that the problem is being solved and there is no issue on the compiler side Cheers -----Original Message----- From: Grégory Jevardat De Fombelle <gregory.jevar...@unige.ch.INVALID> Sent: Tuesday, November 12, 2024 8:38 AM To: Maven Users List <users@maven.apache.org> Subject: [EXTERNAL] RE: RE: Re: maven compiler plugin question I spotted the generated option files in the target folder and the javac.bat script to launch java using this option file. So now I'am even more puzzled as these options files are supposed to solve the too long class path issue ! ...

Actually I wanted to use arg files to solve the too long class path on Windows... I though fork would be enough but there is something else that I don't understand. I checked in the code of the plexus javac compiler and internally it already generates an @option file with all args passed to JVM in fork mode. What is curious is that I don't see this option appearing in command line using mvn -X I just see plain args on the terminal. Any hints ?

I think that the support of "@option-file" syntax is specific to the javac command tool. which would expand this option before to pass it to the compiler. I just verified that "@option-file" is not supported by javax.tools.JavaCompiler. Maven 3 uses the Plexus compiler, but I presume that it doesn't expand that option neither. I don't know if we want to add similar functionality to Maven compiler plugin. But if so, it would be useful to know why options in a file are desired, in order to see if it would be possible to do the same in a more "Maven way".
