define additional source directory in maven

Question

I generate Java sources from a wsdl file. These sources are not under version control (but the wsdl is). We use the cxf-codegen-plugin in maven and the generated classes are generated in <sourceRoot>${project.build.directory}/generated/cxf</sourceRoot>.

This works all fine in maven.

I have to define this directory as addition source directory in Intelij Idea. (targetis normaly excluded).

But every time I re-import the maven project into InteliJ Idea (due to pom changes), I have to manually edit the project structure in Idea and redefine the addition source directory.

Is there any way I can either define this aditional source directory in maven, so Idea picks it up on reload, or tell Idea not to forget the manual source directoy definition?

Answer 1

This case is described in the IntelliJ IDEA Maven FAQ, Generated Sources section:

Specify the directory of your source root when you reimport a project.
You can select one of the following options:

• Detect automatically This is a default option. When you select this option, IntelliJ IDEA automatically detects the location of the generated sources. IntelliJ IDEA also detects which directory to mark as a source root. However, IntelliJ IDEA searches for the generated sources only in target/generated-sources and target/generated-sources/* directories.

• target/generated-sources This option enables you to mark the directory as source root manually.

• subdirectories of "target/generated-sources" This option enables you to mark a subdirectory as a source root manually.

• Don't detect This option lets you skip the detection process.

Take a look at the <add-source> build goal (see an example here)

Quote:

<plugin>
 <groupId>org.codehaus.mojo</groupId>
 <artifactId>build-helper-maven-plugin</artifactId>
 <version>1.4</version>
 <executions>
  <execution>
   <id>add-wsdl-source</id>
   <phase>generate-sources</phase>
   <goals>
    <goal>add-source</goal>
   </goals>
   <configuration>
    <sources>
     <source>${basedir}/src-generated/src</source>
    </sources>
   </configuration>
   <!-- [...] -->
  </execution>
 </executions>
</plugin>
