The problem is that LocationManager.resolvePaths() does a lot more than extracting the module name. It tries resolving all line entries inside module-info.java. If we were to tease apart the different functionality, what would happen? Would we get past the module name extraction but at runtime the JRE would fail with a module load error? From a user perspective I think this would be a much nicer experience. I just don't know how much extra work will be involved to make this happen. > Cannot compile code that depends on on Apache Mina SSH due to JPMS error > > > Key: MCOMPILER-436 > URL: https://issues.apache.org/jira/browse/MCOMPILER-436 > Project: Maven Compiler Plugin > Issue Type: Bug >Affects Versions: 3.8.1 >Reporter: Gili >Priority: Major > Attachments: extract-module-name.zip > > > 1.

[~rfscholte] I get:
bq. InvalidModuleDescriptorException: Provider class

which says nothing about not being able to extract a module name. Are you using
{{ModuleFinder}} to derive a module name? If so, consider changing the error

1. The plugin uses JDK code, the split package is not the issue, but the
service.
2. Yes, now that is illegal
3. It is a JDK message, can't be changed.
To simply check, just run the following line in JShell
{code}
java.lang.module.ModuleFinder.of(java.nio.file.Paths.get("sshd-core-2.5.1.jar")).findAll()

It sounds to me like the plugin should be able to extract a module name from the JAR file even if later on that module cannot be used due to the split package issue. Therefore the first message is misleading and should be corrected. 2. Is it really illegal for a Java Module to reference a service contained in an external module? Assuming both are legal modules (no split package) this should work, right? 3. Can we improve the error message to mention that "although can be used on the classpath, it cannot be loaded on the module path due to split package found in both and "? > Cannot compile code that depends on on Apache Mina SSH due to JPMS error > > > Key: MCOMPILER-436 > URL: https://issues.apache.org/jira/browse/MCOMPILER-436 > Project: Maven Compiler Plugin > Issue Type: Bug >Affects Versions: 3.8.1 >Reporter: Gili >Priority: Major > Attachments: extract-module-name.zip > > > 1.

However, it is not sshd-core that contains this class, but sshd-common. When compiling with the module path, this is verified as well, and it just means that these jars are invalid and must be fixed by sshd. Worst solution is to turn it into a Maven multimodule project, shade both sshd jars into a new jar, and let you other module depend on that on. But as said: let sshd fix this, they created invalid jars (that might work on the classpath, but not on the modulepath anymore) > Cannot compile code that depends on on Apache Mina SSH due to JPMS error > > > Key: MCOMPILER-436 > URL: https://issues.apache.org/jira/browse/MCOMPILER-436 > Project: Maven Compiler Plugin > Issue Type: Bug >Affects Versions: 3.8.1 >Reporter: Gili >Priority: Major > Attachments: extract-module-name.zip > > > 1.

The most straightforward way would be to assign each artifact a unique package (e.g. move all packages of sshd-core under org.apache.sshd.core, all packages of sshd-common under org.apache.sshd.common and so on) but this will break backwards compatibility. Another approach would be to merge any artifacts that split a package. This would retain the same package names but the artifacts would change (this would be a lesser breakage of backwards compatibility but might reduce the modularity of the library). There are many possibilities. Once you decide which way you want to proceed, we can move forward. > Cannot compile code that depends on on Apache Mina SSH due to JPMS error > > > Key: MCOMPILER-436 > URL: https://issues.apache.org/jira/browse/MCOMPILER-436 > Project: Maven Compiler Plugin > Issue Type: Bug >Affects Versions: 3.8.1 >Reporter: Gili >Priority: Major > Attachments: extract-module-name.zip > > > 1.
