Can't pass JVM arguments to runIde task #900

Closed derteufelqwe closed 2 years ago

derteufelqwe commented 2 years ago

Expected behaviour I can somehow add arguments to the JVM.

Actual behaviour Tells me that my Argument is unrecognized

Reproduce the issue

Download a DCEVM java 11 jvm from here https://github.com/JetBrains/JetBrainsRuntime/releases
Download HotswapAgent from here https://github.com/HotswapProjects/HotswapAgent/releases and place it in your java DCEVM install under lib/hotswap/hotswap-agent.jar

In your plugiin under build.gradle.kts add the following

tasks {
...
runIde {
    jvmArgs = listOf("-XX:HotswapAgent=fatjar")
}
...
}

What this should do is to enable hotswap agent for the IDE project for advanced code hotswapping. But with this setup, I get the error that the VM option HotswapAgent is not recognized

How do you specify the JBR you want to use in runIde task?

With the Gradle IntelliJ Plugin v1.4.0, there's the jbrVariant property introduced for that task.

I've taken a look ath jbr and when specifying it correctly, everything works. Thanks. Doesn't the IDE get launched with the same JRE I run the gradle / guild tasks with?

Would you be able to provide the valid config?

runIde task, as well as other ones based on the RunIdeBase, use JbrResolver to find out which Java Runtime to use. There are the following cases checked:

if runtimeDir property was provided and exists
if jbrVersion (and optionally jbrVariant) is set - then download it
if ideDir is set - use bundled JBR
if ideDir is set - download JBR matching the IDE version
and if all of the above cases fail - use the JVM used for running Gradle.
