Error: Could not find or load main class com.tinylabproductions.game_configs.ServerMain

Hi,

Thanks for your report. Does the script work without the set -x (xtrace) option? The error message says

Error: Could not find or load main class com.tinylabproductions.game_configs.ServerMain

Your main class cannot be found. I'm not sure how the debugging option could break this. Please also add

• The version of native-packager you are using
• A small project / build.sbt to reproduce this
• The system you are executing the script

[arturaz]

The -x flag does not impact the failure.

I think it fails because the -cp option the script runs does not escape : in directory names and java uses : as classpath separator.

So -cp foo:bar/a.jar:foo:bar/b.jar becomes foo, bar/a.jar, foo, bar/b.jar as far as java is concerned.

I seem to have the same problem with sbt native packager version 1.4.1 . The generated script calls realpath to get the lib_dir. If the realpath contains a colon somewhere, which is valid in unix filenames, the parameters given to -cp are split the wrong way.

It doesn't depend on the build.sbt file, as far as I can see, so I don't think it's useful to provide build.sbt for reproduction here.

To reproduce, use any project packaged with the native packager, create a directory with a colon in it (eg mkdir /tmp/foo:bar), copy the package into that directory (eg. cp -r package /tmp/foo:bar/) and then call /tmp/foo:bar/package/bin/yourMainClass and it should fail.

Thanks a lot for this great project. After switching from assembly to native packager, I never looked back.

Thanks a lot @felher for the additional information on this. I'll reopen this. If you like to make a pull request, I'm more than happy to help you :smiley:
