Question

I have a dependencies section in my master build.gradle file

subprojects {
   dependencies {
   }
}

Then I add one to my subproject as only that one is using two local dependencies and that breaks everything with the failure below

dependencies {
    compile fileTree(dir: 'play-1.2.4/framework/lib', include: '*.jar')
    compile fileTree(dir: 'play-1.2.4/framework', include: '*.jar')
}

You can’t change a configuration which is not in unresolved state!

googling this error yields lots of results but I can’t seem to decipher from them how to fix this?

NOTE: This did work if I injected the dependencies instead….why is that?

project(':webserver') {
    dependencies {
        compile fileTree(dir: 'play-1.2.4/framework/lib', include: '*.jar')
        compile fileTree(dir: 'play-1.2.4/framework', include: '*.jar')
    }
}

ONE IMPORTANT NOTE: I am not sure if it matters, by my actual master build.gradle is ONE LINE that imports the following one (as I could not get the “master” folder to work out). could that be the problem?

FULL master build.gradle file

    apply plugin: 'java'

    }

Answer 1

This means that you have some other code which resolves (i.e. asks for its files) the compile configuration at configuration time. Something like configurations.compile.each { ... }, outside a task action. After a configuration has been resolved, you can’t add further dependencies to it. Usually it’s undesirable (and unnecessary) to resolve a configuration at configuration time. Among other things, it will slow down your build.

See the Gradle user guide for more information on the distinct phases of a Gradle build (initialization/configuration/execution).
