Apache Marmotta uses Maven to build, test, and install the software. A basic build requires downloading and installing Maven and then running:
mvn clean install
This will compile, package and test all Apache Marmotta modules and install it in your local Maven repository. In case you want to build your own projects based on some of the libraries provided by Apache Marmotta, this usually suffices.
The default loglevel for most unit and integration tests executed during the build is INFO. To change the loglevel for either more or less output, you can pass the loglevel as system property:
mvn clean install -Droot-level=TRACE|DEBUG|INFO|WARN|ERROR
Note that some of the integration tests start up parts of the Marmotta platform during execution. The log level for these tests cannot be changed, as Marmotta is taking over the log configuration in these cases.
Apache Marmotta also includes a default configuration for building a Java Web Application that can be deployed in any Java Application Server. To build the web application, first run
mvn clean install
in the project root. Then change to the launchers/marmotta-webapp directory and run
mvn package
This will create a marmotta.war file in the target/ directory. You can deploy this archive to any Java Application Server by copying it into its deployment directory; more details.
Alternatively, you can directly startup the Apache Marmotta Web Application from Maven with a default configuration suitable for development. To try this out, run
mvn tomcat7:run
wait until the system is started up and point your browser to http://localhost:8080
When developing it is sometimes useful to always start with a clean confi- guration of the system. Therefore, you can also start up the web application as follows:
mvn clean tomcat7:run -Pcleanall
This command will remove any existing configuration directory before startup.
The build environment also offers to automatically build an installer package that guides users through the installation with an easy-to-use installation wizard. The installer is based on izPack and dynamically assembled when building the package. To build the installer, first run
mvn clean install
in the project root. Then change to the launchers/marmotta-installer directory and run
mvn package -Pinstaller
The build process will automatically create an appropriate installer confi- guration from the Maven dependencies through the Apache Marmotta refpack build plugin.
The installer can then be tried out by running
java -jar target/marmotta-installer-x.x.x.jar
Marmotta also comes with support for creating a Docker images that you can use for development or testing:
docker build -t marmotta .
docker run -p 8080:8080 marmotta
An official images is available from Docker Hub as an automated build, so you just need to pull it from there to replace the second step above:
docker pull apache/marmotta
Sometimes it is useful to check if the build runs properly on a clean local repository, i.e. simulate what happens if a user downloads the source and runs the build. This can be achieved by running Maven as follows:
mvn clean install -Dmaven.repo.local=/tmp/testrepo
The command changes the local repository location from ~/.m2 to the directory passed as argument
To test the release build without actually deploying the software, we have created a profile that will deploy to the local file system. You can simulate the release by running
mvn clean deploy -Pdist-local,marmotta-release,installer
Please keep in mind that building a release involves creating digital signatures, so you will need a GPG key and a proper GPG configuration to run this task.
