Error initializing classpath: No subject alternative DNS name matching services.gradle.org found. -> when running grails 3.0.1 app

Question

I created and ran a grails 3.0.1 app at work, but am unable to run it on my personal computer. I followed the same method of installation for grails 3.0.1 (via gvm). The problem seems to be with gradle as grails create-app worked fine. I am also able to compile the application with gradle assemble, but cannot run the application. I am using gradle 2.3.

The complete error looks as follows:

Error Error initializing classpath: No subject alternative DNS name matching services.gradle.org found.
java.security.cert.CertificateException: No subject alternative DNS name matching services.gradle.org found.

Answer 1

gradle/wrapper/gradle-wrapper.properties Change this:

-from: distributionUrl=https\://services.gradle.org/distributions/gradle-2.3-all.zip

-to: distributionUrl=http://services.gradle.org/distributions/gradle-2.3-all.zip

Answer 2

It seems that https://services.gradle.org/'s certificate is messed up

As a temporary workaround you can download the gradle wrapper via http instead of https. For this you have to modify your grails wrapper configuration. I edited build.gradle

task wrapper(type: Wrapper) {
    gradleVersion = gradleWrapperVersion
    distributionUrl = 'http://services.gradle.org/distributions/gradle-2.3-bin.zip'
}

Then generated it by issuing the command: gradle wrapper

After this grails run-app should work.
