compileReleaseKotlin fails with java.lang.ClassNotFoundException: com.sun.tools.javac.util.Context

Question

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:

Using kotlin incremental compilation

IMPORTANT: I'm trying that on Elmentary OS (openjdk1.8.0) and the same project can be run on other computer using Ubuntu

Why do you have classpath 'com.android.tools.build:gradle:...' twice with different versions of the plugin? – Schechinger

just a copy paste error, removed one of them but problems pesists – Koal

Restarting the laptop solved this issue for me – Bathsheba

Related question: 'com.sun.tools.javac.util.Context' class can't be found ('tools.jar' is absent in the plugin classpath). Kapt won't work – Blasien

Answer 1

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!

Koal

openjdk-8-jdk-headless is missing it for some reason. installing openjdk-8-jdk (without the -headless) resolves the issue. – Gamble

Switching to non-headless didn't solve it for me; I had to go Oracle – Jsandye

how to switch into Oracle? – Prostate

Same issue for me and same fix worked. Switching to Oracle on Ubuntu: medium.com/coderscorner/… – Nous

Answer 2

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"

Answer 3

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.

Lecroy

Answer 4

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

Selfsealing

Answer 5

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.

Answer 6

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.)
