java.lang.ClassNotFoundException: com.google.javascript.jscomp.CompilerOptions

Hi,

I am facing this issue whild building ui project with below environment setting -
Java: 8
gradle: 2.14.1
gradle-js-plugin:2.14.1
gradle-css-plugin:2.14.0

My UI project does not have any direct dependency on CompilerOptions.class or closure-compiler-vxxxxxx.jar. Looks like gradle-js-plugin:2.14.1 internally depends on closure-compiler, so it should automatically download required jar.

Please suggest how to overcome this issue. I tried to put latest of closure-compiler-v20160713.jar in my local repo but this also did not yeild any result.

Below is the stacktrace I am getting -

Would you please give a code sample or describe how you're using the JS plugin?

I resolved this problem by putting required JARs on classpath like below -

buildscript {
dependencies {
. . .
classpath (group: "com.google.javascript", name: 'closure-compiler', version: XXX)
classpath (group: "com.yahoo.platform.yui", name: 'yuicompressor', version: XXX)
}}

This problem is only with gradle 2.14, till 2.13 I was not required to put closure-compiler and yuicompressor on classpath.

Can you please explain why it is so? And how it was working till 2.13 version.
