To build the development version of gate-core:
git clone https://github.com/GateNLP/gate-core.git
After this you can run the GUI from the
distro directory as appropriate to your platform (
bin/gate.sh on Linux, open
GATE.app on Mac, or run
gate.exe on Windows). When you update (
git pull), it's the same procedure.
Plugins are no longer part of this
gate-core repository - by default GATE will download its plugins from a Maven repository at runtime (the Central Repository for release versions of GATE, the GATE Maven repository for snapshots) so it is not necessary to build the plugins locally in order to use them.
Each plugin by the GATE team is in its own repository on GitHub (search https://github.com/GateNLP for "gateplugin"), to make changes to a plugin simply clone its repository, make your changes, then
mvn install - GATE will prefer your locally built version over one from a remote repository with the same (SNAPSHOT) version number.
As GATE is distributed via Maven in most cases depending on the relevant release of GATE within your own Maven project should suffice.
If, however, you need to depend, at compile time, on a SNAPSHOT version of GATE, or a plugin from the GATE team which has not yet
been released to Maven central (either a SNAPSHOT or a release that can't be pushed to Central) then you will need to
add the following to the
pom.xml of your project.
<repositories> <repository> <id>gate-repo</id> <name>GATE Repo</name> <url>http://repo.gate.ac.uk/content/groups/public/</url> <layout>default</layout> <releases><enabled>true</enabled></releases> <snapshots><enabled>true</enabled></snapshots> </repository> </repositories>
If you are not using Maven or need to provide the full classpath to a command line script then
./distro directory inside the cloned source code repository contains a file
gate.classpath after running
mvn compile which contains the paths to all the JARs in the Maven cache
that should be put on the classpath when using gate-core from a Java application that embeds GATE.
If GATE was installed using a pre-built distribution, then the distribution directory contains a
directory with all the JAR files that should be included in the class path.
