Sample skeleton project to develop (in Java) and package (as a jar) an Intermediate Representation optimizer plugin for dexdec.
To build, make sure to have JEB_HOME set up to point to your JEB folder, and run one of the build scripts. The output jar will go to out. Copy the jar file to your JEB coreplugins folder.
To develop and debug with Eclipse, run one of the create-eclipse-project scripts to generate the Eclipse project files. You will be able to debug plugin code and use the usual IDE features (auto-completion, javadoc, etc.).
