jdependency's Introduction

jdependency - explore your classpath

jdependency is small library that helps you analyze class level dependencies, clashes and missing classes.

Check the documentation on how to use it with javadocs and a source xref is also available.

Where to get it

The jars are available on maven central. The source releases you can get in the download section.

If feel adventures or want to help out feel free to get the latest code via git.

git clone git://github.com/tcurdt/jdependency.git

How to use it

finding classpath clashes

final Clazzpath cp = new Clazzpath();
cp.addClazzpathUnit(jar1, "jar1.jar");
cp.addClazzpathUnit(jar2, "jar2.jar");

final Set<Clazz> clashed = cp.getClashedClazzes();
for(Clazz clazz : clashed) {
  System.out.println("class " + clazz + " is contained in " + clazz.getClasspathUnits());
}

finding missing classes

final Clazzpath cp = new Clazzpath();
cp.addClazzpathUnit(jar1, "jar1.jar");

final Set<Clazz> missing = cp.getMissingClazzes();
for(Clazz clazz : missing) {
  System.out.println("class " + clazz + " is missing");
}

finding unused classes

final Clazzpath cp = new Clazzpath();
final ClazzpathUnit artifact = cp.addClazzpathUnit(jar1, "artifact.jar");
cp.addClazzpathUnit(jar2, "dependency.jar");

final Set<Clazz> removable = cp.getClazzes();
removable.removeAll(artifact.getClazzes());
removable.removeAll(artifact.getTransitiveDependencies());

for(Clazz clazz : removable) {
  System.out.println("class " + clazz + " is not required");
}
