问题描述:

I already have a working solution where I can specify with maven which classes to not compile when using a particular maven profile.

But I would like to use a general solution and use an annotation instead

The current solution that I have is like

<plugin>

<!-- Exclude some web services used only for internal testing -->

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<configuration>

<optimize>true</optimize>

<excludes>

<exclude>**/something/*ClassPattern.java</exclude>

</excludes>

<testExcludes>

<exclude>**/something/*ClassPatternTest.java</exclude>

</testExcludes>

</configuration>

</plugin>

But Some thing like

@NotCompiledForProduction

would be rather nice on top of a class.

It seems to me that this might be hard (or impossible to do) without changing maven's behaviour. That is not the scope here. And this kind of annotation

you can try this...

<build> <plugins>
  <!-- Run annotation processors on src/main/java sources -->
  <plugin>
    <groupId>org.bsc.maven</groupId>
    <artifactId>maven-processor-plugin</artifactId>
    <executions>
      <execution>
        <id>process</id>
        <goals>
          <goal>process</goal>
        </goals>
        <phase>generate-sources</phase>
      </execution>
    </executions>
  </plugin>
  <!-- Disable annotation processors during normal compilation -->
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <compilerArgument>-proc:none</compilerArgument>
    </configuration>
  </plugin>
</plugins> </build>

You cannot (I assume) use an annotation to determine what source code gets presented to the java compiler, because you need to compile the source code in the first place to process the annotation.

It seems like you need to create different modules in your maven project: one that generates a jar file with the production code, and one module that generates a jar file with testing implementation with a dependency on the production artifact.

If the code really does need to be in the same maven module, then the code should always be compiled. You can however use maven-jar-plugin to create multiple artifacts at the package phase: the default artifactId.jar, and an artifactId-test-lib.jar artifact. You can do this by specifying multiple executions for the plugin, and using <includes> and <excludes> to split the jar files as required.
