How to exclude multiple groups when using dependencies with gradle - gradle

Question

Just like this code:
dependencies {
compile ('com.wdullaer:materialdatetimepicker:3.2.2') {
exclude group: 'com.android.support', module: 'support-v4'
exclude group: 'com.android.support', module: 'design'
}
}
In an android app build.gradle file, when I want to dependency a remote library, how to use exclude group syntax to exclude multiple groups?
Although the code above is a right way, but it`s a little bit complicated.Is there a simpler way?

Answer 1

Well basically 'exclude' is just a method belongs to 'ModuleDependency' class which accepts a 'Map' of 'group' and 'module' and there's no way to pass more.
However you can use 'Groovy' power in this case and for each 'group' from list to call method 'exclude' on 'ModuleDependency' and to pass current 'group'. Take a look at approximate code below.
compile() { dep ->
[group1, group2].each{ group -> dep.exclude group: group }
}

Answer 2

Using this solution with Groovy combinations (Cartesian product) to exclude some list from all configurations:
/**
* These artifacts must be excluded from all configurations and dependencies.
*/
final excludedModules = [
'module-to-exclude-1', 'module-to-exclude-2'
]
/**
* Exclude dependencies from all configurations.
* This configuration solves an issue
* when the same transitive dependency is included by different libraries.
*/
configurations {
[all, excludedModules].combinations { config, moduleToExclude ->
config.exclude module: moduleToExclude
}
}

Example is here:
compile group: 'org.jitsi', name: 'libjitsi', version: '1.0-9-g4b85531', {
[new Tuple('org.opentelecoms.sdp', 'sdp-api'),
new Tuple('junit', 'junit')].each {
exclude group: "${it.get(0)}", module: "${it.get(1)}"
}
}
