Can the Eclipse code style formatter align assignment statements?

问题

Eclipse has an option in Indentation: "Alignment of fields in class declarations" that will align assignments of class members as in:

class Foo {  
   int x    = 3;  
   String y = "abc"  
   long z   = 2;  
}

Is there a setting that will do the same for method level assignments as in:

private void foo() {  
   int x    = 3;  
   String y = "abc"  
   long z   = 2;  
}

I can not find such a setting.

Try creating a new Java Code Style Formatter profile (Window->Prefernces->Java->Code Style->Formatter) or modifying an older one and check Indentation and Braces tabs.

There is no such option in Eclipse, but, as mentioned here, you can use plugin named OCDFormat that aligns assignments and declarations in a selected piece of code.

• Installation: download the latest version of OCDFormat_*.jar from project page on github (click → Raw → Save as) and add it to your Eclipse plugins or dropins directory.

• Usage: select a piece of code and press Ctrl+4.

The Eclipse code style formatter cannot align assignment statements.

columns4eclipse is plug-in that allows you to do so. I had made a gif video illustrating its use but my answer got deleted by a moderator (as >10k users will see), so I let you try the plug-in and see by yourself.
