Maven Copy Files and Folders Plugin not copying linux [dot] ".*" hidden files - linux

Question

I have a maven code
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<execution>
<id>copy-resources-from-parent</id>
<phase>initialize</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>./target/aut-ws</outputDirectory>
<resources>
<resource>
<directory>/prj//workspace-Fm-aut-Testing/</directory>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
This is working fine, but it is not copying .* linux files which are hidden. In normal linux we would use a parameter -a. How to use this here?
Thanks

Answer 1

To disable this behaviour set addDefaultExcludes to false.
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<addDefaultExcludes>false</addDefaultExcludes>
</configuration>
</plugin>
By default files like .gitignore, .cvsignore etc. are excluded which
means they will not being copied. If you need them for a particular
reason you can do that by settings this to false.

In my case ".file" was in target/[unpacked folder] but was missing in final .jar.
I achieved this adding maven-antrun-plugin.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<id>unpack</id>
<phase>package</phase>
<configuration>
<target>
<echo message="repackaging" />
<jar destfile="${project.build.directory}/${project.build.finalName}.jar" basedir="${project.build.directory}/${project.artifactId}" />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
