cd opennlp mvn install
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 17 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
cd opennlp mvn install
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: mvn install
In the opennlp-docs project it is
recommended to always build with mvn clean install because
changed docbook xml files might not be re-processed otherwise.
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.
