e: [kapt] 'com.sun.tools.javac.util.Context' class can't be found ('tools.jar' is absent in the plugin classpath). Kapt won't work

Question

My project is always working fine before, until I upgrade into API 28 And refactor into Androidx. First I think I must solve the problem code because too much the unresolve reference code after refactoring. After I solve many problem, I still getting error

org.gradle.initialization.ReportedException: org.gradle.internal.exceptions.LocationAwareException: Execution failed for task ':app:kaptGenerateStubsDevKotlin'.
    at org.gradle.initialization.DefaultGradleLauncher.doBuildStages(DefaultGradleLauncher.java:145)

    at org.gradle.internal.invocation.GradleBuildController$1.call(GradleBuildController.java:75)

So from gradle console I getting error like this

From that error, I getting error like this

Possible duplicate of compileReleaseKotlin fails with java.lang.ClassNotFoundException: com.sun.tools.javac.util.Context – Consumable

You should check if the bundled java files in the Android Studio Package isn't blocked. Especially if you have to do a new install (zip -> unzip, unblock the downloaded file prior to unzipping) (ie AS3.5C8 -> AS3.5C9 where new install is necessary) – Torres

Answer 1

Did you check your jdk path which folder name contain special symbol like '+', I change to '_'. error be fix. example: folder name is 1.8.0+282 -> 1.8.0_282.

PS: If you use the soft link that: /Library/Java/JavaVirtualMachines/openjdk-8.jdk, you should update the link:

cd /Library/Java/JavaVirtualMachines/
sudo rm openjdk-8.jdk
sudo ln -s /usr/local/Cellar/openjdk@8/1.8.0_282/libexec/openjdk.jdk openjdk-8.jdk

I used homebrew openjdk@8 which was installed at /usr/local/Cellar/openjdk@8/1.8.0+282, can confirm that this + sign made the compilation failed. Changing to a more standard path fixed the issue. – Johannejohannes

Same setup as @Johannejohannes here. Renaming the directory by replacing the + with a _ as suggested by ysjia's answer did the trick. I wonder how you guys figured out this was the issue. – Rathskeller

This was also the fix for me, mostly. However, after I renamed the directory, gradle complained that it couldn't find Java. Therefore I also had to add export JAVA_HOME=/usr/local/Cellar/openjdk@8/1.8.0_302/libexec/openjdk.jdk/Contents/Home and that works. – Udale

Answer 2

enter image description here

I recently had the same problem and solved it in a very simple way, but first I need to contextualize it. In my case I tried to build an app for android directly from the terminal using ./gradlew

So I just ran the commands below on my terminal:

export CLASSPATH=/Library/Java/JavaVirtualMachines/<your_jdk_version>/Contents/Home/lib export JAVA_HOME=/Library/Java/JavaVirtualMachines/<your_jdk_version>/Contents/Home

In my scenario, I was using adoptopenjdk-8.jdk, check which jdk you are using and follow the same principle. You can define an environment variable with these commands as well. But this is the fastest way (but it will never be the only one)
