I use the Eclipse IDE to develop, compile, and run my Java projects. Today, I'm trying to use the
I assume you want to be able to use step-through debugging from Eclipse. You can just run the classes externally by setting the built classes in the bin directories on the JRE classpath.
java -cp workspace\p1\bin;workspace\p2\bin foo.Main
You can debug using the remote debugger and taking advantage of the class files built in your project.
In this example, the Eclipse project structure looks like this:
workspace\project\ \.classpath \.project \debug.bat \bin\Main.class \src\Main.java
1. Start the JVM Console in Debug Mode
debug.bat is a Windows batch file that should be run externally from a cmd.exe console.
@ECHO OFF SET A_PORT=8787 SET A_DBG=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=%A_PORT%,server=y,suspend=y java.exe %A_DBG% -cp .\bin Main
In the arguments, the debug port has been set to 8787. The suspend=y argument tells the JVM to wait until the debugger attaches.
2. Create a Debug Launch Configuration
In Eclipse, open the Debug dialog (Run > Open Debug Dialog...) and create a new Remote Java Application configuration with the following settings:
So, all you have to do any time you want to debug the app is:
