crackercat / java_bytecode_debugger Goto Github PK

It's a bachelor thesis project to supplement the course Nebenläufige Programmierung in UdS.

Watch the introduction video: https://www.youtube.com/watch?v=q7Q7_ex2KuE

Motivation:
    debuggers in IDE (eg. intellij IDEA or eclipse) have step into/over/return
    JDB (the java debugger) has stepi to step one instruction, but no GUI
    This little project combines the two.

current java version:
    13.0.2
    you can change it in build.gradle

to run:
    java -jar build/libs/debuggerGradle.jar
    you should have a java source file to be debugged, but you don't need to compile it, javac and javap are integrated in the project, you just need to click compile after you open the source file
    The integrated javac outputs a class file, the integrated javap outputs a bytecode file, which is a made-up file type and essentially the content of javap's output in the console. Both output will be in the same folder as source code file.
        javac -g Main.java				//-g							   Generate all debugging info
        javap -c -l -p Main.class		//-p  -private                     Show all classes and members
        								//-c                               Disassemble the code
        								//-l                               Print line number and local variable tables

to debug:
    method 1:
    step 1: bash input:
    java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address="8000" -jar build/libs/debuggerGradle.jar
    step 2: in eclipse > debug configurations, choose:
    remote, socket attach

    method 2:
    step 1: in eclipse > debug configurations choose:
    remote, socket listen
    step 2: bash input:
    java -Xdebug -Xrunjdwp:transport=dt_socket,address=127.0.0.1:8000,suspend=y -jar build/libs/debuggerGradle.jar
