Main nar file not in classPath of dependent project.

[Karsten Spang]

I have a JNI shared library written in C and the corresponding Java class in one maven project, and an application using that class in another project. I use the nar-maven-plugin for handling the JNI.

Versions:

Maven 3.6.0

Java 12

nar plugin 3.6.0

The problem is while <type>nar</type> does the trick for dependency resolution, the nar file containing the Java code is not included in the compilation classPath of the dependent project.

I have described the problem in details on Stack Overflow here https://stackoverflow.com/questions/58135663/maven-nar-plugin-nar-file-not-in-classpath-of-dependent-project

The solution is to configure the plugin in the dependent project, e.g. the code in the it0025 example:

      <plugin>
        <groupId>com.github.maven-nar</groupId>
        <artifactId>nar-maven-plugin</artifactId>
        <version>${nar-plugin.version}</version>
        <extensions>true</extensions>
        <executions>
          <execution>
            <id>nar-download</id>
            <goals>
              <goal>nar-download</goal>
            </goals>
          </execution>
          <execution>
            <id>nar-test-unpack</id>
            <goals>
              <goal>nar-test-unpack</goal>
            </goals>
          </execution>
          <execution>
            <id>nar-integration-test</id>
            <goals>
              <goal>nar-integration-test</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
