gradlew assembleRelease Fails With java.lang.ClassNotFoundException: com.sun.tools.javac.util.Context

Sidenote - this post is similar (but not identical) to compileReleaseKotlin fails with java.lang.ClassNotFoundException: com.sun.tools.javac.util.Context, but I thought I'd make my own post with more details about my situation in order to get the best feedback possible. Also, I tried all the solutions in that post, and none of them worked.

I am trying to generate an unsigned release APK for my app. To do that, I use the command gradlew assembleRelease.

I get the following error:

Caught an exception trying to connect to Kotlin Daemon

Here's some more information about my current situation:

I'm using Windows 10.

This is the result of gradlew assembleRelease --scan. It contains a lot of detailed information that could be useful for debugging.

https://scans.gradle.com/s/sohrhovsc676e/

In Android Studio, I went to "File -> Project Structure" and changed my JDK location from

"C:\Program Files\Android\Android Studio\jre" (embedded JDK)

to

"C:\Program Files\Java\jdk1.8.0_172" (JDK 8), which I got from here.

This failed to solve the problem.

I have also added "C:\Program Files\Java\jdk1.8.0_172\bin" to my System Path variable.

I also uploaded my project to Github, incase anyone needs to see it. https://github.com/vedantroy/recyclerview-test

Also, I previously tried replacing implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" with implementation"org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version", but that didn't work either.

Edit 1 -

I tried switching my Build Variant to "release" and then building an APK and that seemed to work. However, I'm not sure if that produces the same result as gradlew assembleRelease

In my case, this started happening after a Java update. It turns out the JRE was updated but the JDK was not.

Try: install the new JDK update, uninstall old versions, and reopen any shell/ps/cmd sessions/windows. It may be necessary to kill existing Gradle daemons but it should be smart enough not to reuse them. Try your build again!
