Building Loom from Maven

[eric at kolotyluk.net]

Thanks, Alan, but even with your settings I still get

 

package jdk.incubator.concurrent is not visible

 

from Maven. More completely…

 

[INFO] -------------------------------------------------------------

[ERROR] COMPILATION ERROR :

[INFO] -------------------------------------------------------------

[ERROR] /C:/Users/ERIC/Documents/git/loom-lab/laboratory/src/main/java/net/kolotyluk/loom/Structured.java:[3,21] package jdk.incubator.concurrent is not visible

  (package jdk.incubator.concurrent is declared in module jdk.incubator.concurrent, which is not in the module graph)

 

What is strange, is that IntelliJ can build and run the code just fine. Usually, I observe that IntelliJ is less stable than Maven.

 

I guess I will keep slogging through Maven Hell a little longer…

 

Cheers, Eric

Has anyone had any success using Structured Concurrency from JDK 19?

 

I have the following pom.xml

 

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <compilerArgs>--source 19</compilerArgs>
        <compilerArgs>--enable-preview</compilerArgs>
        <compilerArgs>--add-modules jdk.incubator.concurrent</compilerArgs>
    </configuration>
</plugin>

 

But when I try to compile the project, I get

 

[ERROR] /C:/Users/ERIC/Documents/git/loom-lab/laboratory/src/main/java/net/kolotyluk/loom/Structures.java:[3,21] package jdk.incubator.concurrent is not visible

[ERROR]   (package jdk.incubator.concurrent is declared in module jdk.incubator.concurrent, which is not in the module graph)

 

And I have been trying for over an hour to fix this but cannot find any solutions that work as they all indicate “--add-modules jdk.incubator.concurrent” should work.

 

This works for me:

          <compilerArgs>
            <arg>--add-modules=jdk.incubator.concurrent</arg>
            <arg>--enable-preview</arg>
          </compilerArgs>
