cics-bundle-maven

A collection of Maven plugins and utilities that can be used to build CICS bundles, ready to be installed into CICS TS.

This project contains:

  • cics-bundle-maven-plugin, a Maven plugin that builds CICS bundles, including Java-based dependencies.
  • cics-bundle-reactor-archetype, a Maven archetype that shows how a simple reactor build can pull together a CICS bundle and a Java project.

Using cics-bundle-maven-plugin

The cics-bundle-maven-plugin contributes a new packaging type called cics-bundle. This is bound to a new build goal that will use the information in the pom.xml and dependencies to create a CICS bundle, ready to be stored in an artifact repository or installed into CICS.

To use the cics-bundle-maven-plugin:

  1. Currently there are no release builds. Snapshot builds are published to the Sonatype OSS Maven snapshots repository. To try a snapshot build, you will need to add the following plugin repository to your pom.xml:

    <project>
  ...
  <pluginRepositories>
    <!-- Configure Sonatype OSS Maven snapshots repository -->
    <pluginRepository>
      <id>sonatype-nexus-snapshots</id>
      <name>Sonatype Nexus Snapshots</name>
      <url>https://oss.sonatype.org/content/repositories/snapshots/</url>
      <snapshots>
        <enabled>true</enabled>
      </snapshots>
      <releases>
        <enabled>false</enabled>
      </releases>
    </pluginRepository>
  </pluginRepositories>
  ...
</project>

  2. Create a new Maven module for the CICS bundle.

  3. Register the plugin to the pom.xml of the CICS bundle module:

    <build>
  <plugins>
    <plugin>
      <groupId>com.ibm.cics</groupId>
      <artifactId>cics-bundle-maven-plugin</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <extensions>true</extensions>
    </plugin>
  </plugins>
</build>

  4. Change the packaging type of the CICS bundle module to the new CICS bundle type:

    <packaging>cics-bundle</packaging>

    If at this point you build the CICS bundle module, it will create a valid CICS bundle! However, it doesn't do much, because it doesn't define any bundle parts.

  5. In the CICS bundle module, define a dependency on another module for a Java project that can be included into CICS, such as an OSGi bundle, WAR, or EAR.

    <dependencies>
  <dependency>
    <groupId>my.group.id</groupId>
    <artifactId>my-web-project</artifactId>
    <version>1.0.0</version>
    <type>war</type>
  </dependency>
</dependencies>

  6. The plugin requires very little configuration. However, an important property for Java bundleparts is the name of the JVM server that the application will be installed into. To define this, alter how you registered the plugin to add some configuration, with the <defaultjvmserver> property:

    <build>
  <plugins>
    <plugin>
      <groupId>com.ibm.cics</groupId>
      <artifactId>cics-bundle-maven-plugin</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <extensions>true</extensions>
      <configuration>
        <defaultjvmserver>JVMSRV1</defaultjvmserver>
      </configuration>
    </plugin>
  </plugins>
</build>

    Now if you build the CICS bundle it will pull in the dependency, add it into the CICS bundle, and define it in the CICS bundle's manifest. The CICS bundle is ready to be stored in an artifact repository or deployed to CICS.

Supported bundlepart types

The cics-bundle-maven-plugin currently supports the following CICS bundleparts:

  • EAR
  • OSGi bundle
  • WAR

Using cics-bundle-reactor-archetype

Maven archetypes provide templates for how a module could, or should, be structured. By using cics-bundle-reactor-archetype, you are provided with a reactor (multi-module build) module, containing a CICS bundle module and a dynamic Web (WAR) module. The CICS bundle is preconfigured to depend on the WAR module. Building the reactor module builds both the children, so you end up with a CICS bundle that contains the built WAR file.

Building the project

The project is built as a reactor project. By running the parent project's build, all the children will also be built.

To build all projects and install them into the local Maven repository, run:

mvn install
