Deleting .class Files

See Also  In most cases, the Clean and Clean All items on the Build menu will meet your needs for deleting .class files. However, if you want to delete .class files that have different names than their associated .java files, you must enable the Parse Class Files property before doing a Clean or Clean All.

To do a simple clean:

1. In the Explorer window, select a folder or file.
2. From the main window, choose Build  Clean or Build  Clean All.

   Build  Clean deletes the sourcename.class in the source's folder. If the compiler's Target property is set, this commands deletes sourcename.class in the appropriate destination folder. If you selected a folder, this command deletes all .class files within the folder. This command does not remove .class files within subfolders or .class files that no longer have a corresponding .java source.

   Build  Clean All is similar to Clean, but removes all .class files within a folder and its subfolders.

To clean .class files that are named differently from their .java files:

1. From the main window, choose Tools  Options.
2. In the Options window, expand IDE Configuration  System  Object Types.
3. Select the Java Source Objects node.
4. Set the Parse Class Files property to True and close the Options window.
5. From the main window, choose Build  Clean or Build  Clean All.

   The IDE inspects every .class file without matching it to a Java source file.

Be careful when enabling this property if you are working with JARs and libraries of classes without source files. Also, it is time consuming for the IDE to recognize .class files that are without a source file.
