Unresolveable custom build extension

    XMLWordPrintableJSON

Details

    Description

      I'm working on a multi-module build and a custom plugin in that build should contribute custom lifecycle and packaging type. Everything works as expected only if I install the plugin in advance and fails resolve the build extension despite the fact that it's a module that is a part of the project. If the custom plugin is not specified as extension then everything works as expected. Here is simple test that showcases the issue:

      /pom.xml
      -------------------------------------------------------------------
      <?xml version="1.0" encoding="UTF-8"?>
      <project xmlns="http://maven.apache.org/POM/4.0.0"

      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

      <modules>
      <module>extension</module>
      <module>consumer</module>
      </modules>

      </project>

      /extension/pom.xml

      <?xml version="1.0" encoding="UTF-8"?>
      <project xmlns="http://maven.apache.org/POM/4.0.0"

      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

      </project>

      /consumer/pom.xml

      <project xmlns="http://maven.apache.org/POM/4.0.0"

      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
      http://maven.apache.org/maven-v4_0_0.xsd">

      <groupId>com.foo</groupId>
      <artifactId>consumer</artifactId>
      <version>1.0.0</version>
      <modelVersion>4.0.0</modelVersion>

      <parent>
      <groupId>com.foo</groupId>
      <artifactId>test</artifactId>
      <version>1.0.0</version>
      </parent>

      <build>
      <plugins>
      <plugin>
      <groupId>com.foo</groupId>
      <artifactId>extension</artifactId>
      <version>1.0.0</version>
      <extensions>true</extensions>
      </plugin>
      </plugins>
      </build>

      </project>

      The above project produces the following error:
      [ERROR] Unresolveable build extension: Plugin com.foo:extension:1.0.0 or one of its dependencies could not be resolved: Failure to find com.foo:extension:jar:1.0.0 in...

      Is this behavior expected? Is there a workaround?
