Sounds like a possible network configuration issue, or a stale/stuck process preventing gradle from running correctly. I'd recommend trying a reboot, or looking around StackOverflow for other possible solutions (note, this issue has likely nothing to do with NativeScript itself):

I already try to reboot 2 3 times but nothing works

[rigor789]

I don't know how to help, though I'm curious about the following info:

• java version
• operating system (I assume Windows?)

[arpitjivanitecan]

Windows 10
java version is jdk-11.0.19.7-hotspot
downloaded from https://adoptium.net/temurin/archive/

[rigor789]

Those look good to me. One thing I would try to see if it makes a difference:

ns clean
ns debug android

If that doesn't work, I would then try the following:

ns clean
ns prepare android

then edit platforms/android/gradle.properties and add to the end of the file

# Disable Gradle Daemon
org.gradle.daemon=false

And then run/build:

ns debug android

[arpitjivanitecan]

output of ns debug android

That seems like a completely different issue - post your package.json with the dependencies, seems like incorrect project setup? How was this project created?

Did the above help in the updated version? Are you able to run the following:

ns create myApp --ts
cd myApp
ns debug android --no-hmr

?

The webpack issue is because you had @nativescript/webpack@^4.1.0 in the package.json, but trying to use the 5.x api/interface.

[arpitjivanitecan]

Still getting the same error if you have time then you can lookup into my system I can give you remote access for some time

[arpitjivanitecan]

Problem solved with changing jdk from jdk-11.0.19.7-hotspot to jdk-11.0.18

[rigor789]

Good to know, thanks for the update!
