Error trying to run example #2

Closed Edward205 closed 3 years ago

Edward205 commented 3 years ago

I just downloaded the example and when i try to run it i get this error:

Launching lib\main.dart on ASUS I006D in debug mode...

FAILURE: Build failed with an exception.

* What went wrong:
Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 683ms
Exception: Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

I'm using visual studio code and trying to run on phyiscal android device. I searched on google and one possible fix was to change the line distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip from gradle-wrapper.properties to distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-all.zip , but that didn't work and resulted in a huge error. Any help is appreciated, thanks.

Hi @Edward205, right now I am running java 11 for one of my projects, I will need some time to upgrade to your android build tools config to replicate the issue. Meanwhile, is it possible you can try to downgrade to java 11 and test.

Edward205 commented 3 years ago

@ManuSekhon I will try that end tell you if it worked. Thanks

Hi @Edward205, I have updated the old packages and migrated code to null safety. Should solve this error. Please take the latest pull from 'main' branch, flutter clean, and try to run again. Please let me know if this persists.
