Eclipse: Change general to Java project

Problem: Migrate a Eclipse general project to a Eclipse Java project

Solution: add the java nature

  1. Close your project.
  2. Open your project file (which is located in your root directory of the appropriate project) called .project with your default editor. Search for
    and change it to
    Save the changed file.
  3. Open the project again – now it’s a java project.
