Unpack inner zips in zip with Maven - maven

I can unpack zip file via the maven-dependency plugin, but currently I have the problem that inside that zip file other zip files are include and I need to unpack them as well. How can I do this?

You can unzip any files using ant task runner plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<id>prepare</id>
<phase>validate</phase>
<configuration>
<tasks>
<echo message="prepare phase" />
<unzip src="zips/archive.zip" dest="output/" />
<unzip src="output/inner.zip" dest="output/" />
<unzip dest="output">
<fileset dir="archives">
<include name="prefix*.zip" />
</fileset>
</unzip>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>

Using ANT is not cool any more ;)
http://maven.apache.org/plugins/maven-dependency-plugin/examples/unpacking-artifacts.html
Sample code for unpacking zip (archive.zip) file:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>unpack</id>
<phase>process-resources</phase>
<goals>
<goal>unpack</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>foo</groupId>
<artifactId>archive</artifactId>
<version>1.0-SNAPSHOT</version>
<type>zip</type>
</artifactItem>
</artifactItems>
</configuration>
</execution>
</executions>
</plugin>
File archive.zip should be installed into maven repository first. For example with task Attach artifact
org.codehaus.mojo:build-helper-maven-plugin:build-helper:attach-artifact

TrueZIP Maven Plugin also works well. Sample config:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>truezip-maven-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<id>copy-package</id>
<goals>
<goal>copy</goal>
</goals>
<phase>package</phase>
<configuration>
<verbose>true</verbose>
<fileset>
<directory>outer.zip</directory>
<outputDirectory>${project.build.directory}/outer</outputDirectory>
</fileset>
<fileset>
<directory>${project.build.directory}/outer/inner.zip</directory>
<outputDirectory>${project.build.directory}/inner</outputDirectory>
</fileset>
</configuration>
</execution>
</executions>
</plugin>
Official examples

You can also use the plugin dependencies.
There is a goal to unpack dependencies (see http://maven.apache.org/plugins/maven-dependency-plugin/unpack-dependencies-mojo.html)

How to remove a a specific directory from the Maven's target directory at the end of the build?

I have a task to unpack all the jars mentioned in the pom.xml and then jar the unpacked content into one single jar. I am able to do this using the unpack-dependency goal of the dependency plugin and the jar plugin.
However, after i generate the new jar, I want to delete the folder that was created after unpacking. I am using the following code snippet in my pom.xml(Please read the comments above each plugin).
<build>
<plugins>
<!-- This part of the code is used to unpack all the dependencies mentioned in my pom.xml -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.10</version>
<executions>
<execution>
<id>unpack-dependencies</id>
<phase>package</phase>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<configuration>
<includes>**/*.class</includes>
<outputDirectory>${project.build.directory}/alternateLocation</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>true</overWriteSnapshots>
</configuration>
</execution>
</executions>
</plugin>
<!-- This part of the code is used for creating a jar with all the contents of the "alternateLocation" directory above -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classesDirectory>${project.build.directory}/alternateLocation</classesDirectory>
<outputDirectory>${project.build.directory}</outputDirectory>
<finalName>abc</finalName>
</configuration>
</execution>
</executions>
</plugin>
<!-- I am using this part of the code to delete the "alternateLocation" after everything is done, but it deletes the target directory instead -->
<plugin>
<artifactId>maven-clean-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>auto-clean</id>
<phase>install</phase>
<goals>
<goal>clean</goal>
</goals>
<configuration>
<filesets>
<fileset>
<directory>${project.build.directory}/alternateLocation</directory>
</fileset>
</filesets>
<excludeDefaultDirectories>${project.build.directory}</excludeDefaultDirectories>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
The clean plugin is basically deleting the target directory by default.
So how can I delete the "alternateLocation" folder from the target directory at the end of the build. (I guess you can do it using the maven-antrun-plugin but i don't want to use this plugin.).
You can solved this by using the maven-assembly-plugin via the predefined descriptor jar-with-dependencies which can be done by the following:
<project>
[...]
<build>
[...]
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.6</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
[...]
</project>
Than you don't need supplemental configuration.

Maven: Build tar.gz file with externally downloaded files

What I'm trying to do with maven is build a project.tar.gz file with some data in the ./data folder downloaded from some location on the web.
project.tar.gz
data
somefile.txt
some_other_file.zip
Currently I'm trying to approach this using the assembly plugin, so far without much success.
So far the following works: I download a file to target/data
But now I need that file packaged in a tar file.

I personally wouldn't use Maven for this; Maven is a tool for standard processes. What you want to do is very special.
Have a look at the Maven AntRun Plugin or use Ant directly. That way, you can create a script which does exactly what you want without fighting with Maven's conventions all the time.

Move a config file into etc folder(of Karaf) when a (Maven)bundle is deployed

I want to move a cfg file into the etc folder of karaf whenever a bundle is deployed.
the cfg file is in under src/main/resource .i tried the following in the pom but its not working.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<phase>deploy</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<echo>Using env.test.properties</echo>
<copy file="src/main/resources/test.cfg" tofile="${env.KARAF_HOME}/etc/test.cfg"/>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
How can i do it ?
One of the solution could be:
- put your test.cfg file in a more specific folder. (eg: src/main/resources/cfg)
- use the maven resources plugin
This is a working example based on the maven phase generate-resources (replace that phase by deploy in your case):
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<execution>
<id>copy-to-karaf</id>
<phase>generate-resources</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<resources>
<resource>
<directory>src/main/resources/cfg</directory>
<filtering>true</filtering>
</resource>
</resources>
<outputDirectory>D:\apache-karaf-3.0.1\etc\</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>

How to place the output jar into another folder with maven?

I'd like to place my output jar and jar-with-dependencies into another folder (not in target/ but in ../libs/).
How can I do that?
You can use the outputDirectory parameter of the maven-jar-plugin for this purpose:
<project>
...
<build>
<plugins>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.1</version>
<configuration>
<outputDirectory>../libs</outputDirectory>
</configuration>
</plugin>
...
</plugins>
</build>
...
</project>
But as cdegroot wrote, you should probably better not fight the maven way.
If you want to copy the artifact into a directory outside your project, solutions might be:
maven-jar-plugin and configure outputDirectory
maven-antrun-plugin and copy task
copy-maven-plugin by Evgeny Goldin
Example for the copy-maven-plugin is:
<plugin>
<groupId>com.github.goldin</groupId>
<artifactId>copy-maven-plugin</artifactId>
<version>0.2.5</version>
<executions>
<execution>
<id>deploy-to-local-directory</id>
<phase>install</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<skipIdentical>false</skipIdentical>
<failIfNotFound>false</failIfNotFound>
<resources>
<resource>
<description>Copy artifact to another directory</description>
<targetPath>/your/local/path</targetPath>
<directory>${project.build.directory}</directory>
<includes>
<include>*.jar</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
Another way would be maven-resources-plugin (find the current version here):
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.0.2</version>
<executions>
<execution>
<id>copy-files-on-build</id>
<phase>package</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${basedir}/[TO-DIR]</outputDirectory>
<resources>
<resource>
<directory>[FROM-DIR]</directory>
<!--<include>*.[MIME-TYPE]</include>-->
<filtering>false</filtering>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
I would do it this way:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<phase>install</phase>
<configuration>
<target>
<copy file="target/${project.artifactId}-exec.jar" tofile="../../docker/${project.artifactId}.jar"/>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
This technique worked well for me:

I specially like the solution using maven-resources-plugin (see here) because is already included in maven, so no extra download is needed, and also is very configurable to do the copy at a specific phase of your project (see here to learn & understand about phases). And the best part of this approach is that it won't mess up any previous processes or build you had before :)
<project>
...
<build>
<plugins>
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>3.2.0</version>
<executions>
<execution>
<id>copy-resources</id>
<!-- here the phase you need -->
<phase>validate</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>/dir/where/you/want/to/put/jar</outputDirectory>
<resources>
<resource>
<directory>/dir/where/you/have/the/jar</directory>
<filtering>false</filtering>
<includes>
<include>file-you-want-to.jar</include>
<include>another-file-you-want-to.jar</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
...
</build>
...
</project>
Of course you can also use interpolated variables like ${baseDir} and other good stuff like that all over your XML. And you could use wild cards as they explain here
Maven dependency plugin is perfectly capable of copying all dependencies and just built artifact in a custom location. Following example will copy all runtime dependencies and a built artifact in a two execution phases.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.3.0</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<includeScope>runtime</includeScope>
<outputDirectory>${project.build.directory}/jars</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
<execution>
<id>copy-artifact</id>
<phase>package</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>${project.groupId}</groupId>
<artifactId>${project.artifactId}</artifactId>
<version>${project.version}</version>
<type>${project.packaging}</type>
</artifactItem>
</artifactItems>
<outputDirectory>${project.build.directory}/jars</outputDirectory>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
While documentation of dependency plugin states in its documentation that in order to copy built artifact you have to use any phase after the package phase, that is not true if you are building jars. In that situation you can use package phase. At least in 3.3.0 version of plugin.

Copying files from my project in Maven

Is it possible to copy folders from my project to a certain location during some Maven phase? Does anybody know how?
The Maven way of doing this would be using the copy-resources goal in maven-resources-plugin
From http://maven.apache.org/plugins/maven-resources-plugin/examples/copy-resources.html
<project>
...
<build>
<plugins>
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>2.7</version>
<executions>
<execution>
<id>copy-resources</id>
<!-- here the phase you need -->
<phase>validate</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${basedir}/target/extra-resources</outputDirectory>
<resources>
<resource>
<directory>src/non-packaged-resources</directory>
<filtering>true</filtering>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
...
</build>
...
</project>
Take a look at the maven-antrun plugin. You can copy a file in any maven phase like this:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<id>copy</id>
<phase>compile</phase>
<configuration>
<tasks>
<copy file="myFileSource" tofile="MyFileDest"/>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
A solution similar to #mort's one with maven-antrun-plugin 1.8:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<id>copy</id>
<phase>compile</phase>
<configuration>
<target>
<copy file="sourceFile" tofile="targetFile"/>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
Note that <tasks> node is deprecated in favor of <target> node as of maven-antrun-plugin 1.5.
