如何强制特定依赖项在 gradle 中使用特定版本的库

Question

I have a dependency 'com.liferay.mobile:liferay-screens:2.1.4' and I want to force it for example to use 'com.android.support:support-v4:28.0.0' . How can I do this force only for liferay-screens dependency in gradle?

I've done it like below but it takes error:

ERROR: Could not find method com.liferay.mobile:liferay-screens:2.1.4() for arguments [build_e4u81lzxji4bi1lau20a1sng2$_run_closure3$_closure7@2be4e1d1] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

implementation 'com.liferay.mobile:liferay-screens:2.1.4' {
    resolutionStrategy.force 'com.android.support:support-v4:28.0.0'
}

In Gradle 6.0, my recommendation would be to use the new strictly semantics in a constraint :

dependencies {
    implementation 'com.liferay.mobile:liferay-screens:2.1.4'
    constraints {
        implementation('com.android.support:support-v4') {
            version {
                strictly '28.0.0' // Will make sure that library uses that version in your build
            }
        }
    }
}

Prior to Gradle 6.0, your way would be the recommended one, but the syntax needs to be adapted:

dependencies {
    implementation 'com.liferay.mobile:liferay-screens:2.1.4'
}
configurations.all {
    // Will force that dependency version everywhere
    resolutionStrategy.force 'com.android.support:support-v4:28.0.0'
}

There is effectively no point in forcing a version only in a given context, as you tried to express. What matters is that you want to overall resolution to always use that specific version.
