React-native: Andoid app showing error ":app:compileDebugJavaWithJavac FAILED "

[sankhadeeproy007]

Hi, I seem to have followed all the steps given in your docs correctly. I also got the iOS app to work, but I'm getting this error whenever I try to run it in android.

Any help would be appreciated.

[sankhadeeproy007]

Solved! A new project with a different name fixed it.

[3210jr]

hi @sankhadeeproy007 did you just create a new project and copy over your files or what?
Thanks..

[sankhadeeproy007]

No, it happened with a new project. However I did create a new project and copied some files over later in another project.

[Calvein]

It should be documented somewhere, you can't create a react-native project called native (I just had the same problem).

[sahas-]

It just happened to me. I started a hello world project but ended up doing more there.. finally, wanted to move them over. Created a new project with RN init and copied my assets over. npm install installed all dependencies and react-native run-android fails with this error "app:compileDebugJavaWithJavac FAILED". Any workarounds apart from recreating the project with different name?

[srisk94]

I might be late but this may help to others also.yesterday I came across asame issue then I changed sdk versions in gradle file ,problem solved :)

[parkerproject]

You creating a new project and new name doesn't look like a real solution to this.

Seems there is a bug in android studio, i got the same error when i started a new project, in my case, it happens because i choose scrolling activity first by mistake, and then i go back with the previous button, choose empty activity with a name MainActivity. After i clicked the finish button, the stupid AS create an activity called MainActivity, but instead of activity_main.xml in layout folder, there was the content_scrolling.xml has been created.

[zubairahmad2]

no problem, thank to all for reply i have solved this issue last time.

If you have Android studio, then try open the android code, and run 'project' ==> 'clean', or just do cd android & ./gradlew clean, probably solve the issue.

[aeruhxi]

cd android & ./gradlew clean solves it but it slows down every build. Isn't there a proper fix to this?

[akshaydoiphode]

Please help me solve error With nativescript with JavaScript. When I tried to built project it gives this error. I tried some of above solutions. But nothing works for me.

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

[nmerchant]

Also running into this. Had a project running successfully on another machine, cloned my repo to this machine, and as far as I can tell I have everything set up correctly but still getting this pop up. Running ./gradlew clean from the Android folder also doesn't seem to do anything.

[sumitsavla]

I was getting same issue -> failed for task ':app:compileDebugJavaWithJavac'.

Updating react-native-fbsdk to 0.7.0 in package.json fixed it for me! :)

[amrlabib]

Try the this stack overflow answer Basically clear global .gradle cache

I solved this issue by deleting the .gradle folder inside the android folder.
