GitWrapper

A set of classes for working with git repositories. The repository is examined using a wrapper around native git calls.

The current feature set is limited.

Setup

GitWrapper uses the Gradle build system.

Using ./gradlew build will assemble a .jar file containing the library in the build/libs directory. The dependencies of the library may be displayed using ./gradlew dependencies --configuration compile.

If the project using the library is also a gradle project it is far more convenient to add the library as a sub-project. The code below assumes that the directory of your clone of GitWrapper is a sibling of the project directory using it. Extend your settings.gradle and build.gradle as follows:

settings.gradle

#!groovy
includeFlat 'GitWrapper'

build.gradle

#!groovy
dependencies {
    compile project(':GitWrapper')
}

Example

The following example code will clone a given repository to the current working directory and display the SHA1 hashes of all merge commits.

#!Java
GitWrapper git;

try {
    git = new GitWrapper("git");
} catch (ToolNotWorkingException ex) {
    // Handle that case that git can not be called using the supplied command.
    return;
}

Optional<Repository> optRepo = git.clone(new File("."), "A VALID GIT REPOSITORY URL", false);

optRepo.ifPresent(repo -> repo.getMergeCommits().forEach(mergeCommit -> {
    System.out.println("Merge Commit: " + mergeCommit.getId());
}));
