I have several artifacts from the same groupId (org.webjars
), and I need to unpack them, and then copy all the contained js files into the same directory.
The artifacts archives have a hierarchy (compressed as a jar) as follows:
artifact1
- resources
- webjars
- ...
- sample-1.js
- sample-2.js
I need at the end that every js file is copied into the same directory without their hierarchy, as follows:
outputDirectory
- sample-1.js
- sample-2.js
- ...
- sample-n.js
The result I can reach is the following one:
outputDirectory
- artifact-1
- resources
- webjars
- ...
- sample-1.js
- sample-2.js
- ...
- artifact-m
- resources
- webjars
- ...
- sample-n.js
For this purpose, I used the maven-dependency-plugin
:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>unpack org.webjars dependencies</id>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<configuration>
<includeGroupIds>org.webjars</includeGroupIds>
<includes>**/*.js</includes>
<outputDirectory>${project.build.directory}/static</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
Is there a magical option of this plugin to do this, or should I need another plugin to complete the job?
EDIT: Here is the solution I finally used:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<id>copy org.webjars dependency to jar</id>
<phase>package</phase>
<goals><goal>run</goal></goals>
<configuration>
<target>
<copy todir="${project.build.directory}/classes/static" flatten="true">
<fileset dir="${project.build.directory}/static">
<include name="**/*.js"/>
</fileset>
</copy>
</target>
</configuration>
</execution>
</executions>
</plugin>
<!-- Force the generation of the jar to be done after the javascript dependencies have been copied.
Note : This is a half solution, as the jar is generated twice: a first time before the javascript get copied, and
another one after. As a result, there is the correct jar, but after two creations... -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<id>Force the jar-plugin to be called after the javascripts dependencies have been copied to be embedded</id>
<phase>package</phase>
<goals><goal>jar</goal></goals>
</execution>
</executions>
</plugin>
You could use the maven antrun plugin by using the copy task with the flatten option as it is described in the following thread: Maven : copy files without subdirectory structure
Best
You can use file mappers described in Maven Dep. plugin "Rewriting target path and file name" : I was able to use ist like so:
<execution>
<id>include-run-java-sh-for-docker</id>
<phase>package</phase>
<goals>
<goal>unpack</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>io.fabric8</groupId>
<artifactId>run-java-sh</artifactId>
<version>1.3.8</version>
<classifier>sources</classifier>
<includes>**/fp-files/*.sh</includes>
<outputDirectory>${project.build.directory}/jkube</outputDirectory>
<fileMappers>
<org.codehaus.plexus.components.io.filemappers.FlattenFileMapper />
</fileMappers>
</artifactItem>
</artifactItems>
