How to use Dagger in non-Android Gradle Java application?

Question

Dagger is advertised as "A fast dependency injector for Android and Java". But I'm not able to make it run without Gradle 'android' plugin.

compile 'com.squareup.dagger:dagger:1.2.1'
provided 'com.squareup.dagger:dagger-compiler:1.2.1'

There is no provided in 'java' or 'application' gradle plugin I'm using. It is even mentioned in this bug report.

Making it both 'compile' yelds no result. The same java.lang.IllegalStateException: Module adapter for class ... could not be loaded. is thrown.

How gradle with 'java' and 'application' can be configured to use dagger annotation processor?

Answer 1

It should work fine with both defined as compile. The error indicates other problem with your code.

If you still want to use provided scope please read this: http://www.sinking.in/blog/provided-scope-in-gradle/

Quick example how to use provided:

apply plugin: 'java'

configurations {
    provided
}

sourceSets {
    main {
        compileClasspath += configurations.provided
    }
}

dependencies {
    provided 'com.google.guava:guava:18.0'
}
