running flutter app got Execution failed for task ':bluetoothadapter:compileDebugJavaWithJavac'

I didn't change anything in my Flutter application and it was running perfectly but when i tried running on real device i got this exception
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':bluetoothadapter:compileDebugJavaWithJavac'.
> Could not find tools.jar. Please check that C:\Program Files\Java\jre1.8.0_321 contains a valid JDK installation.
BUILD FAILED in 13s
Exception: Gradle task assembleDebug failed with exit code 1
Check out this post for a workaround:
tools.jar seems to be not in Android Studio classpath on Windows 8
It seems, the tools.jar is not present on every version of Java 8 anymore. Also make sure to use a JDK and not a pure JRE for development.
Maybe it is worth downloading a current version of the JDK from https://adoptopenjdk.net

why do I get Gradle task assemble Debug failed error

I imported a flutter project from GitHub. when I tried to run it I had this error(no errors in code). I could not figure out what this error is all about and I keep getting this error for every project which I import from GitHub.Please help me out!
This is the error:
Exception in thread "main" java.util.zip.ZipException: error in opening zip file.
Gradle threw an error while trying to update itself. Retrying the update...
Finished with error: Gradle task assembleDebug failed with exit code 1.
It's kinda common problem when you get a project from github and I solved it once with this answer.
Copy paste from there:
Open your Android Studio preferences(Command + ',') and go to
Languages and Frameworks -> Dart
Check "Enable Dart support for the project your_project_name"
In "Dart SDK path" click in "…" and navigate to flutter SDK directory.
Under that directory you'll find "bin/cache/dart-sdk". This is the
dart sdk path you should use.
Click "Apply"
flutter packages get
flutter run

Flutter get error "Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain"

I'm trying to run my project , I am getting error
Launching lib/main.dart on Android SDK built for x86 in debug mode...
Running Gradle task 'assembleDebug'...
Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
Exception: Gradle task assembleDebug failed with exit code 1
It is hard to know the problem with so little information. One general approach with worked to me was performing:
flutter clean
Try to run.
If it does not run delete the jar file under android/gradle/properties to recompile it and try again.

gradle eclipse integration -

I'm using a eclipse 4.2 distribution and have installed the gradle eclipse integration plugin from springsource.
When I initially try to create a quick java project with the wizard I get the following error:
Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at C:\devtools\gradle-1.4\docs\userguide\gradle_daemon.html
Please read below process output to find out more:
-----------------------
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Could not fetch model of type 'HierarchicalEclipseProject' using Gradle installation 'C:\devtools\gradle-1.4'.
When I run gradle build in the command line everything's fine.
Any ideas how i could get this to work?
Cheers
Since you can run gradle in command line successfully, you would want to try to use that gradle in the eclipse plugin.
Set Preference -> Gradle -> Gradle Distribution -> Folder to your own gradle distribution that runs fine.
