Indenting Java source files using Eclipse

Question

I'm using an UML tool that generates Java classes from the UML class diagram. Unfortunately the code inside is not indented.

How to solve this? How can I indent a file using Eclipse?

Answer 1

How to indent a Java source file in Eclipse:

1. Open the file in Eclipse's text editor.
2. Ctrl+A to select all text.
3. Ctrl+I to indent the text (or right click > Source > Indent).
4. Ctrl+S to save the file.

Done.

(If you also want to correct the spacing, then use Ctrl+Shift+F or right click > Source > Format. This can be applied to a single file, or a group of files using the Project Explorer pane.)

Answer 2

ctrl + a and then ctrl + i

Answer 3

In fact, you can make the whole process fully automatic by invoking Eclipse plugin from command line:

eclipse -nosplash \
  -application org.eclipse.jdt.core.JavaCodeFormatter \
  -verbose \
  -config ~/eworkspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.jdt.core.prefs \
  MyClass.java

Just make sure to create workspace where you have your formatting preferences set up according to your requirements.

Answer 4

Use the code format feature with the shortcut Ctrl+Shift+F in eclipse then you will get the code formatted using eclipse standard and not only indenting. Advanced you can write an xml file to specify your formatting preferences.
