# Adding an outjar

The AspectJ outjar setting enables building a project into a JAR file, rather than a folder.

To set the outjar:

1. Select the AspectJ project in the Package Explorer
2. Right click and select AspectJ Tools > Configure AspectJ Build Path...
3. Select the Output jar tab
4. In the Output jar text field type a name for the JAR file.
5. Click OK to finish. If automatic building is switched on the project will rebuild and the JAR file will be created.
