why xml files in eclipse project's source directory is not copied to target/classes directory?

buildpath, eclipse, eclipse-project-file, maven, xml

Solution

Maven is by default looking for resource files i.e. *.xml, *.properties and etc. in `src/main/resources` directory. It is recommended to put your resource files under here.

However, nothing prevent you from putting resource files somewhere else, for instance, `src/main/java/org/wpse/db/config/`, as some people prefer to put resource files along with class file under special package, you just need a little more configuration in pom.xml:

<build>
  <resources>
    <resource>
      <!-- This include everything else under src/main/java directory -->
      <directory>${basedir}/src/main/java</directory>
      <excludes>
        <exclude>**/*.java</exclude>
      </excludes>
    </resource>
  </resources>

  ... ...
</build>

By default configuration, when running `mvn eclipse:eclipse` it generates following .classpath file:

<classpath>
  <classpathentry kind="src" path="src/main/java" including="**/*.java"/>
  ... ...
</classpath>
... ...

When importing into Eclipse, it gives you following classpath (what you don't want):

Using the pom configuration above, when running 'mvn eclipse:eclipse' it generates following .classpath file:

<classpath>
  <classpathentry kind="src" path="src/main/java"/>
  ... ...
</classpath>
... ...

When importing into Eclipse, it gives you follwing classpath (what you want):
