Where do you configure Eclipse Java compiler (javac) flags?

Question

Ex.

javac -g ButtMonkey.java

Where do you configure the -g flag when Eclipse compiles Java source? (Using Ganymede but I doubt that has changed in later versions so any answer probably helps.)

What I need is:

-g

Generate all debugging information, including local variables. By default, only line number and source file information is generated.

Was hoping someone would get a kick out of that. lol – Douville

Answer 1

Select the menu: Window > Preferences > Java > Compiler

There you will find several check boxes under the heading "Classfile Generation".

Oh sneaky, they hide the actual flags from you. Was afraid I was going to have to create a custom builder! – Douville

@Douville Note that Eclipse uses its own built-in Java compiler (which is not exactly the same as javac from the JDK), so there isn't one checkbox which exactly matches what -g on javac does. – Sporogony

Answer 2

For Eclipse version Photon Release (4.8.0)(Build id: 20180619-1200), Enabling (or disabling) the debug flag in Eclipse IDE,

1. Window > Preferences > (left option) Java > Compiler
2. (section) 'Classfile Generation'
3. (checkbox) 'Add variable attributes to generated class files (used by the debugger)' // Checking this checkbox will enabled the debug flag. Unchecking this checkbox will disable it.
