Subject [jira] [Created] (MSHADE-374) Exclude test shading when shadeTestJar is enabled
Date Tue, 07 Jul 2020 07:13:00 GMT
Yana Vasileva created MSHADE-374:
------------------------------------

             Summary: Exclude test shading when shadeTestJar is enabled
                 Key: MSHADE-374
                 URL: https://issues.apache.org/jira/browse/MSHADE-374
             Project: Maven Shade Plugin
          Issue Type: Task
    Affects Versions: 3.2.4, 3.2.3
            Reporter: Yana Vasileva


*Scenario:*
 * Plugin version - 3.2.3 (I tried with 3.2.4 as well)
 * Maven version - 3.2.5 (old one, so I tried with 3.6.3 as well - same result)
 * Project A shades some libraries - `httpclient`, `commons-coded`, `commons-logging`
 * {{shadeTestJar}} is enabled so the created `projectA-tests.jar` can resolve the shaded
source classes
 * The plugin configuration looks similar to the following:

{code:java}
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <configuration>
          <promoteTransitiveDependencies>false</promoteTransitiveDependencies>
          <createSourcesJar>true</createSourcesJar>
          <createDependencyReducedPom>true</createDependencyReducedPom>
          <keepDependenciesWithProvidedScope>true</keepDependenciesWithProvidedScope>
          <relocations>
            <relocation>
              <pattern>org.apache.http</pattern>
              <shadedPattern>myjar.impl.org.apache.http</shadedPattern>
            </relocation>
            <relocation>
              <pattern>org.apache.commons.codec</pattern>
              <shadedPattern>myjar.impl.org.apache.commons.codec</shadedPattern>
            </relocation>
            <relocation>
              <pattern>org.apache.commons.logging</pattern>
              <shadedPattern>myjar.impl.org.apache.commons.logging</shadedPattern>
            </relocation>
          </relocations>
          <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"
/>
          </transformers>
          <shadeTestJar>true</shadeTestJar> 
        </configuration>
      </plugin>
{code}
 

As a result, `projectA-tests.jar` includes the shaded classes from the `commons-codec-tests.jar`
and `commons-logging-tests.jar` which cause troubles when some of the tests scenarios are
being executed for project A.

*Question:*
Is it possible to exclude the classes of `commons-*-tests.jar` and prevent their shading in
the `projectA-tests.jar`?

I tried the following as it is documented [here|https://maven.apache.org/plugins/maven-shade-plugin/examples/includes-excludes.html],
however, the classes are still shaded:
{code:java}
          <artifactSet>
            <excludes>
              <exclude>commons-codec:commons-codec:tests</exclude>
              <exclude>commons-logging:commons-logging:tests</exclude>
            </excludes>
          </artifactSet>
{code}
Is the observed behavior expected? Is there any way to exclude the tests shading?

Any help is highly appreciated, please let me know if I need to provide some further information.
