Import a broken JAR into Anypoint Studio 7.x

You may find yourself in a situation in which you have a Mule 4 deployable archive ("JAR" extension file) but you are unable to import it into Anypoint Studio 7, and that may lead to many hours searching for the current production version or someone with the right config.

In this article, I'll explain how to import a broken JAR into Anypoint Studio 7.x.

It's important to understand that with "broken JAR" I meant a JAR file that Studio 7.x is not recognizing as a valid deployable archive to import it through the wizard. With "broken JAR" I don't mean to import a file that has been corrupted like a download file that was not downloaded completely.

... or read the step by step:

The easiest way I've found to rebuild the Studio project using a broken JAR file, is the following:

1) Create a new project and delete the Mule configuration file (automatically created XML file in /src/main/mule)

2) Open the new project folder in your file manager app (Finder, explorer, etc.). We'll call this folder "destination"

3) Now, rename your JAR file into ZIP file and uncompress it into a new folder in your computer (any folder). We'll call this "source" folder

4) It's now time to move the files from "source" to "destination" in the following way:

• source/META-INF/maven/<org>/<artifact>/pom.xml into destination folder
• source/* (except META-INF and "repository" folders) into destination/src/main/resources

5) Finally, refresh your Studio project, and move the Muley icon files (XML Mule Configuration files) from /src/main/resources to /src/main/mule

Optional

In case the Mule project contains dependencies outside your current repositories/files, they will be available in the source/repository folder, and you may install them using Maven or Anypoint Studio's "Install artifact in local repository" option. This option should only be used if the API fails to run due to missing dependencies.
