SYMPTOM

You are trying to import a JAR file into Anypoint Studio as a Packaged Mule Application. However, in the "Mule Import from Deployable Archive" window, you see the following message: "The file does not contain any projects to import".
Import Mule Project error

CAUSE

This happens because Studio expects a certain project structure embedded within the JAR file. Applications packaged through Maven must have a special flag set on the build in order to be re-importable to Studio 
mvn clean package -DattachMuleSources
Exporting the JAR from Studio adds this flag by default when choosing Attach Project Sources.
 

SOLUTION

If you have access to the original project, export the app choosing Attach Project Sources to include metadata that Studio requires to reimport the deployable file as an open Mule project into your workspace. You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace as stated in the documentation. 

If you do not have access to the project, you will have to rebuild the project structure so that Studio can import this from the pom.xml.
Follow these steps:
  1. Extract the contents of the JAR file with an unzipping tool.
  2. Inside that folder, create the minimum required folder structure src/main/mule and src/main/resources
  3. Move any XML files that contain Flows or Config elements to src/main/mule. Check for any sub-folders containing such files and move the entire folder inside.
  4. If the archive contains any Java Class files, create a folder structure src/main/java and move all Java class files there. Check for any sub-folders containing such files and move the entire folder inside.
  5. Move any other files or folders from your project which do not contain Flows or Config elements to src/main/resources, but do not move or modify the META-INF and repository folders.
  6. Open the META-INF/maven folder and locate the application's pom.xml file inside the sub-folders. Move the pom.xml file into the root folder so that it is on the same level as repository, src and META-INF.
You can now import the app into Studio by going to Import > Anypoint Studio project from File System. Select the root folder where the pom.xml is located, enable the Copy project into workspace option and click Finish.

If you have any missing dependencies error, you will need to import these custom dependencies manually from the repository folder. Each dependency can be found in repository/groupID/artifactID/version/ and can be installed to your Local Repository by following the article <Installing libraries and connector manually into maven local repository for use by Anypoint Studio>. You will not need to add the dependency to the project's pom file, as it is already there.
