You can't change configuration 'gwtBuild' because it is already resolved? - gwt

Question

I have set up a multi folder project with build.gradle file as shown in https://github.com/Catalysts/catalysts-gradle-plugins/wiki/cat-gwt ,here is /baseDir/build.gradle
apply plugin: 'cat-gwt'
dependencies {
gwtBuild (
[project(path: ':proj1', configuration: 'gwtCompile')]
)
}
subprojects {
// apply plugin: 'xxx'
sourceSets {
main {
java {
srcDir 'src'
}
resources {
srcDir 'src'
}
}
}
}
gwt {
modules {
projectX {
modulename = 'cc.catalysts.gwt.example.projectX'
}
}
}
but while running the gradle build I get the following error.
