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!

Migration to Gradle plugin v.1.1.2 caused failing lint checks

My team recently decided to use newly announced unit-testing integration in Android studio, which requires upgrading Gradle plugin version to 1.1.0 or higher. But this update caused failing of Lint task for one of our modules, with very weird error. Can anyone give an idea what might be a problem here?

To gather all the dependencies, you can just “copy” the configuration that represents the dependencies you want.
For example, to copy all the compile time and runtime dependencies you could do something like:
task copyToLib(type: Copy) {
into "$buildDir/output/lib"
from configurations.runtime
}
you can also use gradle.user.home system property property or --gradle-user-home command line property

[2014-10-06 09:10:43 - Pdf2jpg-V3] Dx 1 error; aborting

To import the gradle project to my android project i tried in two ways:
1- Exporting a JAR from the gradle project and importing as external jar and checking it with the build path
2- adding the whole gradle project to the build path from the android project.
Both throws the same exception.

Finally the problem was the compliance level in the Gradle proeject (1.8), so, i updated the project to 1.6 (like my android project) and also updated the instances that were working only in 1.8 to be now working in 1.6.
My problem now is that it seems that the jar references included in the gradle project are not working, but in fact theay are included are gradle references as below:
So, the execution throws class not found exception:
java.lang.NoClassDefFoundError: javax.json.JsonObject
...Though javax.json is included, any idea??

GwtApplication: exception: walljumper/tools/Assets
walljumper/tools/Assets
and says this in the console

Thanks in advance

In your Something.gwt.xml in your shared project do you correctly list the translatable source packages?
<module>
<source path="walljumper/" />
</module>
