8 I have a Gradle project in Ubuntu. It's written in Java 14. I have the Java 14 JDK installed. When I build it from the command line, everything works, but no one wants to use a command line! When I open it in IntelliJ Idea, it throws an error: * Where: Initialization script '/tmp/ijmapper.gradle` * What went wrong: Could not compile initialization script '/tmp/ijmapper.gradle`. > Startup failed: General error during semantic analysis: Unsupported class file major version 60. followed by a long, unhelpful stack trace that says a lot about Groovy. (The project is not a Groovy project; it's a Java project.) Major version 60 refers to Java 16, which this project is not using. I've already gone into Project Structure and made sure that it...

In my setup the Intellij Flutter plugin doesn't support Java code. It treats Java classes like text files. Is there any way I could get Intellij to support me with the Android specific Java code? (type checks, completion suggestion, imports, refactoring...) Here is my flutter doctor output: [✓] Flutter (on Linux, channel master) • Flutter at /home/*****/flutter/flutter • Framework revision 99ca38e988 (4 days ago), 2017-03-01 13:15:48 • Engine revision 74de13c0bd • Tools Dart version 1.23.0-dev.2.0 [✓] Android toolchain - develop for Android devices (Android SDK 25.0.2) • Android SDK at /home/*****/Android/Sdk • Platform android-25, build-tools 25.0.2 • ANDROID_HOME = /home/*****/Android/Sdk • OpenJDK Runtime Environment (build 1.8.0_121-b13) [✓] Android Studio (version 2.2) • Android Studio at /opt/android-studio • Gradle version 2.14.1 [-] WebStorm (version 2016.3) • Flutter plugin not installed; this adds Flutter specific functionality....

When I am trying to use 'Refactor - Extract - flutter widget' option in Intellij idea for refactoring a code in a widget, I am getting following error. Server error: Invalid parameter 'params.kind'. Expected to be RefactoringKind; found ""EXTRACT_WIDGET"". There is no solution available on internet for this.

I wanted to try out flutter with IntelliJ, so I followed the order of https://flutter.io/setup-macos/ and everything worked out. But today, out of nowhere, it doesn't work anymore. I can run my code, but reload and hot reload is disabled. So I'd have to close and restart everything, everytime, I'd like to see a change. "flutter doctor" tells me: IntelliJ IDEA Ultimate Edition (version 2017.2.5) ✗ Flutter plugin not installed; this adds Flutter specific functionality. • Dart plugin version 172.4155.35 • For information about installing plugins, see https://flutter.io/intellij-setup/#installing-the-plugins But I looked it up, and flutter clearly was installed. I honestly sit here for 5 hours now, trying to figure it out, but I just can't find the problem. I deleted and reinstalled Flutter, Dart and IntelliJ like 4 times now, but it didn't work either. Flutter in generall works, at least I can run the app in terminal, so the problem got to be with IntelliJ....
