creating a tar archive from maven deploy - maven

Question

I am trying to use maven v3 to create a tar.gz output for a non-Java project in order to deploy to nexus. I cannot specify tar in the packaging option in my pom file. Unless mistaken, I can specify tar as an option for packaging when running mvn deploy. Is there anyway I can specify that in the pom file itself?

Answer 1

You can create the TAR.GZ file and "attach" it to the primary artifact. I have an example to repackage a WAR into Linux service on GitHub. The key steps are to package the assembly:
<project ...>
...
<build>
<pluginManagement>
<plugins>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
<configuration>
<attach>true</attach>
<formats>
<format>tar.gz</format>
</formats>
<descriptorSourceDirectory>src/main/assemblies</descriptorSourceDirectory>
</configuration>
</plugin>
...
</plugins>
</pluginManagement>
<plugins>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
</plugin>
...
</plugins>
</build>
</project>
<attach>true</attach> installs the artifact. The assembly in this case is:
<?xml version="1.0" encoding="UTF-8"?>
<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.0.0
http://maven.apache.org/xsd/assembly-2.0.0.xsd">
<id>bin</id>
<baseDirectory>${artifactId}-${version}</baseDirectory>
<files>
<file>
<outputDirectory>bin</outputDirectory>
<source>
${project.build.directory}/${project.build.finalName}.jar
</source>
<filtered>false</filtered>
<destName>${artifactId}.jar</destName>
</file>
</files>
<fileSets>
<fileSet>
<outputDirectory>bin</outputDirectory>
<directory>${project.basedir}/src/bin</directory>
<includes>
<include>${artifactId}.conf</include>
</includes>
<filtered>true</filtered>
</fileSet>
</fileSets>
<dependencySets>
<dependencySet>
<outputDirectory>lib</outputDirectory>
<useProjectArtifact>false</useProjectArtifact>
<includes>
<include>*:*-x86_64:*</include>
</includes>
<scope>runtime</scope>
<outputFileNameMapping>
lib${artifact.artifactId}.${artifact.type}
</outputFileNameMapping>
</dependencySet>
</dependencySets>
</assembly>
but you'll need to find/create one appropriate for your use-case.
