Bundling plugins with Hudson

If you'd like to ship plugins pre-installed in hudson.war, you can do so by placing your plugins inside hudson.war as /WEB-INF/plugins/*.hpi.

These files will be extracted whenever Hudson is started. This feature is new in Hudson 1.259.

Sample

Here is a maven pom to build a hudson webapp bundled with your plugins

<dependencies>

		<dependency>
			<groupId>org.jvnet.hudson.main</groupId>
			<artifactId>hudson-war</artifactId>
			<version>${org.jvnet.hudson.version}</version>
			<type>war</type>
		</dependency>

	</dependencies>

	<build>
		<plugins>

			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-dependency-plugin</artifactId>
				<executions>
					<execution>
						<phase>generate-sources</phase>
						<goals>
							<goal>copy</goal>
						</goals>
					</execution>
				</executions>
				<configuration>
					<artifactItems>
						<artifactItem>
							<groupId>${pom.groupId}</groupId>
							<artifactId>my_plugin1</artifactId>
							<version>${pom.version}</version>
							<type>hpi</type>
							<outputDirectory>${project.build.directory}/plugins</outputDirectory>
						</artifactItem>
						<artifactItem>
							<groupId>${pom.groupId}</groupId>
							<artifactId>my_plugin2</artifactId>
							<version>${pom.version}</version>
							<type>hpi</type>
							<outputDirectory>${project.build.directory}/plugins</outputDirectory>
						</artifactItem>
					</artifactItems>
				</configuration>
			</plugin>

			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-war-plugin</artifactId>
				<configuration>
					<webResources>
						<resource>
							<directory>${project.build.directory}/plugins</directory>
							<targetPath>WEB-INF/plugins</targetPath>
						</resource>
					</webResources>
				</configuration>
			</plugin>


		</plugins>
	</build>

Here is an Ant target that bundles all the plugins in the ./plugins subdirectory into a new hudson.war file.

<?xml version="1.0" encoding="UTF-8"?>
<project basedir="." name="Hudson-Bundle">

    <property name="src.war" value="download/hudson.war" />
    <property name="dist" value="dist" />
    <property name="plugins.dir" value="plugins" />
    
    <target name="bundle" description="Merge plugins in ./plugins into a custom hudson.war">
        <mkdir dir="${dist}" />
        <zip destfile="${dist}/hudson.war">
            <zipfileset src="${src.war}" />
            <zipfileset dir="${plugins.dir}" prefix="WEB-INF/plugins" />
        </zip>
    </target>

    <target name="distclean">
        <delete dir="${dist}" />
    </target>

</project>
