Normally you don't want to include debugging data in a release JAR, nor do you usually want to go through a JAR build each time you run. That's what :lwjgl3:run
is for, though it is a good habit to build JARs periodically and test them. In IDEA, there's a run button next to a debug button, and they should work for any run configuration -- for :lwjgl3:run
, using debug allows hitting breakpoints and the like. You probably know this, but the run button is a green triangle, and the debug button is usually next to or near it, as a green bug icon with several legs.
If debugging using that button, on the Gradle task for :lwjgl3:run
, isn't working, it sounds like a bug or regression in IDEA, since that has worked in the past reliably. I would not be at all surprised if there is some problematic interaction with some recent Android Gradle Plugin version, since that has caused issues before (even in non-Android modules).
If the run
task for any module isn't working but jar
is, there may be some other issue with how the build is set up, or maybe how IDEA imported it. Normally I recommend running jar
tasks early but not necessarily all the time, since checking if a JAR works can help notice issues like mismatched case in filenames. The run
task seems to start more quickly, and since it works on your source code, it is able to debug and hit breakpoints. I don't know if there is any performance/memory effect from the -g
compiler flag and debug setting.
I'll leave this open for comment; I might add a debugJar
task that includes this if there is demand.
I'm not sure what adding -g and debug would do to a JAR (probably make it a little larger), but for the run task, they don't hurt the performance much, if at all.
I checked this here: https://github.com/tommyettinger/Sonorant/commit/e280c70287feabadaffba2c8dc8925bfbd46eb5c#diff-740191ccb94660b9e650981359e8034dbc04ce36f512dcf03bc0731239c136d5
That's a GPU-bound application, so if the debug flag has some CPU-side cost, this wouldn't be affected.
I do not know whether there is an exisiting gradle task defined by your program to include debugging information when compiling the source code. But, after asking Artificial Intelligence, I found out it is suggesting, this line of code in the lwjgl3 module.
tasks.withType(JavaCompile).configureEach
{ options.debug = true options.compilerArgs += ["-g"] }`.And then, in Intellij Idea Community Edition, I can set up my run/debug configuration, I choose JAR application, and fill up the necessary parameters, and I can then debug my libgdx app.
Because I am getting used to compiling my source code using the command
gradlew :lwjgl3:jar
. This way, I can compile my code into .class and package them into .jar file.Initially, I thought, by default, It will include the debug information as well when compiling, but it is not. That is why when I tried to debug my app, it shows weird behaviour such as not stopping program execution at a breakpoint specified in Intellij Idea.
If there is any task that is pre-built in gradlew task that will include debug information, please let me know thank you.
