Execution failed java.io.IOException: Is a directory
I'm trying the simplest configuration possible. This is just by adding the plugin, I haven't even created a module-info.java in the test directory yet.
When I run:
mvn clean install -e
I get the following error:
By debugging the error is that it's trying to access the compiled classes in the target folder, but at the time of execution they haven't been compiled yet. Am I doing something wrong?
This is my full list of plugins in case there's some incompatibility I don't know of with some of them:

Seems like the plugin tries to read a non-existent module-info.test file. Looking into it...
Can you please try using the JAVA executor in your pom.xml?

Hey @sormuras,
I actually tried even before posting here. The outcome was the same, even though the stacktrace was slightly different.
Below is the full outcome. It seems the plugin is running during the classes compilation time, even in the case where tests are skipped.

Found the underlying issue:
https://github.com/sormuras/junit-platform-maven-plugin/blob/01d12f7bda2442bb0924af7e6701f373ce55da20/src/main/java/de/sormuras/junit/platform/maven/plugin/JUnitPlatformMojo.java#L547-L554
The empty string "" is treated as the "current working directory". Fix in progress...
Since I face the same bug (and this is my first time I try testing in the Java module world), I wonder what the workaround is?
IIRC, the work around was to provide some kind of a test/java directory. Either an empty one, or one with at least a single test, or one with with modul-info.test file.
Need to re-investigate this issue. Perhaps, I'll rewrite the plugin anyway, "soon"™.
[...] first time I try testing in the Java module world [...]
Have a look (and copy) the directory structure of the modular-world... integration tests at: https://github.com/sormuras/junit-platform-maven-plugin/tree/master/src/it -- they still should work.
