The purpose of the OpenEngSB Maven Plugin is to provide additional useful goals for the development of the OpenEngSB itself and all projects which base on the OpenEngSB. It helps in various goals starting in assembling, checkstyle, license checking and many other various goals which would otherwise require to duplicate tons of version (and manage it in addition) between the OpenEngSB and projects which are based on the OpenEngSB.

To use the openengsb-maven-plugin in your project add the following configuration to your project's pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.openengsb</groupId>
        <artifactId>openengsb-maven-plugin</artifactId>
        <version>${openengsb.maven.plugin.version}</version>
      </plugin>
    </plugins>
  </build>
  ...
</project>       
        

The plugin can now be invoked via mvn openengsb:<goal>

assemble or etc/scripts/assemble.sh

Installs the OpenEngSB and skips tests. Furthermore a nightly profile is activated if available in your poms.

eclipse or etc/scripts/eclipse.sh

Generates eclipse configuration file for the module where it is invoked from and all submodules. The generated eclipse projects are also configured to use the checkstyle rules shipped with the plugin (see checkstyle mojo).

checkstyle

Performs a Checkstyle check of the project. The checkstyle configuration file which is used for the check can be found here. We ship this configuration file with the plugin (and changes need to be done there) because we think it may be useful for other OpenEngSB related projects. Setting up eclipse projects with configured checkstyle becomes very easy that way (simply mvn openengsb:eclipse).

genConnector or etc/scripts/gen-connector.sh (For additional info how to create a connector see ???)

Guides interactively through the creation of a connector and generates the artifact via the connector archetype.

genDomain or etc/scripts/gen-domain.sh (For additional info how to create a domain see ???)

Guides interactively through the creation of a domain and generates the artifact via the domain archetype.

licenseCheck or etc/scripts/license-check.sh

Performs a check if appropriate license headers are available in every source file. The licenseCheck mojo wraps the com.mycila.maven-license-plugin. A large part of the default behavior of this mojo can be changed in src/main/resources/license/licenseConfig.xml. See this site for available configuration options. The openengsb-maven-plugin needs to be reinstalled after changing its default behavior.

NOTE: pom.xml files are excluded from license check

Parameters:

licenseFormat or etc/scripts/license-format.sh

Adds a license header to files where the license header is missing. Regarding the configuration for this mojo the same applies as for licenseCheck.

NOTE: pom.xml files are excluded from license format

Parameters:

prePush or etc/scripts/pre-push.sh

Builds and installs the openengsb, checks for license headers, performs a Checkstyle check and runs the integration tests.

Parameters:

provision or etc/scripts/run.sh / etc/scripts/quickrun.sh

Equivalent to execute karaf or karaf.bat per hand after build by mvn clean install in a (typically) assembly directory.

Parameters:

These parameters are typically configured in the pom of your assembly project (/assembly/pom.xml for the OpenEngSB)).

pushVersion or etc/scripts/push-version.sh

Updates the development version.

Parameters:

extractSource

The goal is a really powerful for including source code into the documentation. It recursively scans all files on a defined path for specific comments in the code and extracts the source in between into a soruce listing which could be included afterwards easily. Currently the plugin scans the following files: .java, .xml, .properties and .cfg. To start an exclude in java your code needs to look like...

    // @extract-start javaout
    private App() {
    }
    // @extract-end

... The format of the comments have to be eactly of the format as shown in the sample. "javaout" could be replaced on the other hand with whatever you like. A file will be created in the target folder with the name of your choice ("javaout" in this case) containing the content between the comments. In addition the "programlisting" and the correct language tag is attached. This allows to directly include the code which is also compiled for your project, to be included into the documentation.

For xml a simple example would look like:

<blueprint>

  <!-- @extract-start xmlout -->
  <service id="abc" interface="a.b.c">
    <bean class="a.b.d" />
  </service>
  <!-- @extract-end -->

</blueprint>

Property files and cfg files are of exactly the same format and would need to look like:

# @extract-start propout
timetablePageName=Timetable
# @extract-end

Parameters:

releaseNightly or etc/scripts/release-nightly.sh

Mojo to perform nightly releases. This mojo activates the nightly profile in the project, where you can put your additional configuration for nightly releases (To see what these profiles can be necessary for please read the descript of the other release mojos).

release<XXX> (You can find a detailed description of the OpenEngSB release process in ???)

The release<XXX> mojos (except Nightly) wrap the maven-license-plugin, basically just invoking mvn release:prepare and then mvn release:perforn with some useful default configuration which can be reused for other projects related to the openengsb. These mojos perform a release and activate the <XXX> profile. These release profiles are important and are required to ..

Parameters:

Goals:

Sources for documentation are extracted using the org.openengsb.openengsbplugin.ExtractDocSourceMojo. The mojo itself includes a list of implementations of the org.openengsb.openengsbplugin.extract.AnnotatedSourceExtractor interface.
