compilation failed "Task :app:compileDebugJavaWithJavac FAILED"

this error randomly popped up after i tried running my ionic cordova app. this not only happens on my branch ive been working on but also with every other branch i try to run, which leads me to believe it is something with my machine. ive tried restarting and reinstalling the packages and it hasnt solved the issue.

i think you are missing these v4 libraries or dependencies are not getting sync properly. first thing you can invalidate/restart(file menu in Android studio) your project and if still not working then can check below link: package android.support.v4.app does not exist ; in Android studio 0.8

Flutter/Dart - FlutterFirebaseMessagingPlugin.java - Build fails with Exception "error: cannot find symbol"

After upgrading to Null Safety sdk: ">=2.12.0 <3.0.0" I'm getting errors when I try to build my Flutter app in Android Studio.

Android Studio tells me FlutterFirebaseMessagingPlugin.java "cannot find symbol". So what does this mean and how do I fix it

Update your firebase_messaging in pusbpec.yaml to version that supports null-safety (for example: firebase_messaging: ^10.0.0, and call flutter pub get from terminal

First, get the latest versions of your firebase dependencies from pub.dev
Run the commands:
flutter pub upgrade
flutter pub get
flutter clean
Invalidate caches and restart
and then try running the app

For me, the problem was that I updated androidx core version from 1.0.1 to 1.5.0 in my app/gradle file but I didn't update it in project level gradle file in resolutionStrategy
They both should be the same.

Javac compilation error

I am trying to compile a Java class but I get this error:
TestRunner.java

It is unable to resolve any of the import packages and classes.
I'm not sure what is wrong?
Thanks

Got the same error, but
Closing android studio,cleaning the build and again rebuilding it solved my error.

error: package org.picketlink.idm.internal does not exist

I changed my pom.xml to add picktlink-social so I changed my pom to remove picketlink-deltaspike, and addeda apache deltaspike because I had some redundancy issues with picktlink detlaspike, and for a while my app worked.
So every once in a while when I did a mvn clean, I got this error

So I changed the version of picketlink from 2.6.1 to 2.6.0 or 2.6.0 to 2.6.1 and it compiled again. But now that is not even working,
This is my pom.xml http://pastebin.com/9bRMrGkv.
org.picketlink.internal should be in picketlink-impl module, which is included in my pom.xml
This is my IDMConfiguration.java http://pastebin.com/XES0WyDQ
http://pastebin.com/XES0WyDQ
I did a jarscan and found this

----------------------------------------------

I had the same problem when I updated the picketlink version. I checked your pom and I realized that it contains
<dependency>
<groupId>org.picketlink</groupId>
<artifactId>picketlink-api</artifactId>
</dependency>
which specifies all the dependencies, but you have also added each module separately. So, I think you should delete them and try again.
