Please refer to the Migration Guide when upgrading from 2.5.1 to 3.0.0+

For Maven:

<dependency>
    <groupId>com.github.javaparser</groupId>
    <artifactId>javaparser-core</artifactId>
    <version>3.5.6</version>
</dependency>

For Gradle:

compile 'com.github.javaparser:javaparser-core:3.5.6'

How To Compile Sources

If you checked out the project from GitHub you can build the project with maven using:

mvn clean install

If you checkout the sources and want to view the project in an IDE, it is best to first generate some of the source files; otherwise you will get many compilation complaints in the IDE. (mvn clean install already does this for you.)

mvn javacc:javacc

If you modify the code of the AST nodes, specifically if you add or remove fields or node classes, the code generators will update a lot of code for you. The run_metamodel_generator.sh script will rebuild the metamodel, which is used by the code generators which are run by run_core_generators.sh Make sure that javaparser-core at least compiles before you run these.
