Gradle Android，从其他模块中排除依赖关系

Question

I have an Android app, who I want to unit test. With the MVP pattern, I was able to extract a lot of classes outside of the "android world" in order to test them as plain unit tests (with Junit) inside a separate module[1]. However, I would like to log some messages from those classes. So I have tried to use slf4j-api with the android binding. With the intention to provide the simple binding on my tests. But the " test " module start with complaining that there are two slf4j binding in the classpath and that he is using the android-binding.

So my question is, How can I exclude the slf4j-android dependency from the " test " module ? Here is the build.gradle of my " test " module

evaluationDependsOn(":app")

apply plugin: 'java'

dependencies {
    def app = project(':app')

    testCompile project(path: ':app', configuration: 'debugCompile')

    def debugVariant = app.android.applicationVariants.find({it.name == 'debug'})
    testCompile debugVariant.javaCompile.classpath
    testCompile debugVariant.javaCompile.outputs.files
    testCompile files(app.plugins.findPlugin("com.android.application").getBootClasspath())

    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    testCompile 'org.powermock:powermock-api-mockito:1.6.1'
    testCompile 'org.assertj:assertj-core:1.7.1'

}

Answer 1

Use the "exclude" attribute to remove dependent libraries. Something like the following:

testCompile 'junit:junit:4.12' { exclude 'slf4j-android' }

I'm not sure which library you need to exclude it from. To find out, use gradle to list the library dependencies.

gradle dependencies
