Building from Source
- If you have an IDE installed such as NetBeans or Eclipse installed, it will make your development easier. However, follow on for the brave.
- At least JDK 8 is required to compile and run the object code.
- At least Apache Maven 3.3.9 is required to build the source files and assemble the project.
OpenNLP can either be build from the distributed sources or from a subversion checkout. These build instructions document how to build from the latest trunk version. The distributed source package includes a README file which explains how to build it.
On the first checkout everything should be built. Go to the opennlp folder inside the trunk folder (e.g. opennlp-trunk) and type
to build all modules. The build installs the maven artifacts in the local repository and creates a binary and source distribution inside the opennlp-distr/target folder.
After the initial build the individual modules can be built on their own with:
In the opennlp-docs project it is recommended to always build with
because changed docbook xml files might not be re-processed otherwise.
mvn clean install
In some cases it might be convenient to skip the tests. That can be done with the "-Dmaven.test.skip=true" option. For example type:
mvn clean install -Dmaven.test.skip=true
No tests will be executed.
It might happen from time to time that the build fails, if so please report a broken build on the opennlp-dev mailing list. The build should always work for everyone.
