I'm trying to build my Android Project (which contains a library module) via terminal using gradlew. From within Android Studio, it compiles and installs successfully but, when I try to run ./gradlew assembleDebug I get the following stacktrace:

IMPORTANT: I'm trying that on Elmentary OS (openjdk1.8.0) and the same project can be run on other computer using Ubuntu
OK, problem is with JDK, I was using Open JDK 8 and it was missing tools.jar for some reason, I switched to Oracle JDK and now it works like a charm!
I solved it only by replacing in build.gradle this
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.2.30"
with this:
implementation "org.jetbrains.kotlin:kotlin-stdlib:1.2.30"
I got this exact issue on Windows when the JDK bin directory was not in my PATH.
The process is documented here: http://docs.oracle.com/javase/7/docs/webnotes/install/windows/jdk-installation-windows.html#path
If you have windows, change your PATH so that it includes C:\Program Files\Java\jdk1.8.0_151\bin instead of C:\ProgramData\Oracle\Java\javapath
Yeah, it might break in an update or whatever, but considering that an update broke my machine... At least you're in control now.
My guess is that C:\ProgramData\Oracle\Java\javapath points to the non-jdk jre, thus failing to find javac-specific jars.
I've figured out that on CentOS 7 this error cab be caused by absence of right java package. So, instead of yum install java-1.8.0-openjdk I used yum install java-1.8.0-openjdk-devel and it worked. On Ubuntu there is no devel packege, but I hope this answer helps anyway.
The problem is due to C:\ProgramData\Oracle\Java\javapath which points to the non-jdk jre, thus failing to find javac-specific jars. Please remove it with C:\Program Files\Java\jdk1.8.0_171\bin (for e.g.)
