Gradle Error: No method add() found for arguments

Question

So I'm adding a custom plugin to Gradle, specifically jmeter. https://github.com/kulya/jmeter-gradle-plugin

I thought everything worked, but now this error is occuring:

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\rstraubel\Documents\DataCentral\build.gradle' line: 21

* What went wrong:
A problem occurred evaluating root project 'DataCentral'.
> Could not find method add() for arguments [jmeterEditor, class com.github.kulya.gradle.plugins.jmeter.JmeterRunGuiTask] on task set.

Line 21 is just where I call plugin: 'jmeter' Everything else specified in the github has been done. Any ideas? Thanks

Edit: Full Build.gradle

    mavenCentral()
    maven { url "http://repo.spring.io/libs-milestone"}

    classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    classpath("com.github.kulya:jmeter-gradle-plugin:1.3.1-2.6")
}
}

Answer 1

Most likely, the jmeter plugin hasn't been updated to support Gradle 2.0. You can verify by trying with 1.12.
