Description

Hi,
I have several directories located in the src/test/resources and I
need them to be copied to target/test-classes. This is of course handled
by maven-resources-plugin, however it does not copy empty directories. I
know it sounds insane to access empty dirs using classloader but I have
my reasons

Not insane at all we have a valid reason for wanting to do the same thing.

I have patched the resources plugin to take a new parameter includeEmptyDirectories just add the following configuration:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-zip-plugin</artifactId>
<version>2.2</version>
<extensions>true</extensions>
<configuration>
<includeEmptyDirs>true</includeEmptyDirs>
</configuration>
</plugin>

If the directory is empty then it will appear in the output. If the directory is not empty and a filtering rule excludes all its files it will NOT appear in the output.

Any chance this patch will be included soon ?
I also need these empty directories and the current behaviour is different from eclipse behaviour.

Until this issue is fixed, here is a workaround I've been using successfully. Add this plugin element into project/build/plugins in your pom.xml, and change the dir in the mkdir task.

You can have multiple <mkdir> elements for multiple directories. The mkdir task does nothing if the directory has already been copied by the resources plugin.

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<id>create-empty-directory</id>
<phase>process-classes</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<mkdir dir="$

{basedir}

/target/classes/empty" />
</tasks>
</configuration>
</execution>
</executions>
</plugin>

This originally came from the openejb-standalone pom.xml in the openejb project.

Fix uses different configuration:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.3</version>
<configuration>
<includeEmptyDirs>true</includeEmptyDirs>
</configuration>
