… picker CoGo could not run a plain Java or Kotlin program: Quick Run builds and installs an Android app. JVM-Tools adds, for a folder of .java/.kt files with no Gradle build: - Run: compiles every source on the device (kotlin-compiler-embeddable from the IDE's local Maven repository for Kotlin, then the JDK's javac, so Java and Kotlin can use each other) and execs java on the chosen main class. Output streams to Build Output; Cancel Run stops the JVM. Unsaved Java/Kotlin buffers are written before compiling. - Run configuration: lists every class with a main (Java static main, Kotlin top-level main as its FileNameKt facade, @JvmStatic main in an object or companion) and takes program arguments with shell-style quoting. It is a Material dialog built on the IDE activity and shown through PluginWindows, so it matches the IDE's dialogs. Saved per project in the plugin directory. - A Java/Kotlin Program template. The Gradle actions and Quick Build are hidden in these projects, as in Python-Tools. Requires 26.37 for PluginWindows. Programs cannot read stdin: plugin commands have no input stream.

There was a problem hiding this comment.
main is attributed to the last class/interface/enum/record declared anywhere before it in the file, so a nested type declared above main takes the name.
Example:
public class Main {
record Point(int x, int y) {}
public static void main(String[] args) {}
}This yields Point, so the script runs java -cp … Point and fails with "Could not find or load main class Point". A main inside a static nested class is likewise run under its simple name rather than Outer$Inner.
The Kotlin @JvmStatic path (ownerOf, line 70) has the same issue with nested objects. No test in MainClassFinderTest covers nested types.

Adds JVM-Tools: run Java and Kotlin programs the way a desktop IDE does. In a folder of
.java/.ktfiles with no Gradle build:javac) and runs the chosen main class. Output goes to Build Output; Cancel Run stops it.PluginWindows.Gradle actions and Quick Build are hidden in these projects, as in Python-Tools. Requires CoGo 26.37. Programs can't read keyboard input; plugin commands have no stdin.
Verified on an emulator: Kotlin, Java and mixed projects, arguments, cancel, unsaved edits, tooltips and help page, 2x font, and Android projects left unchanged.
