I am trying to solve the problem,
I have some dependencies declared in build.gradle file for my android app, but the problem is that a lot of these dependencies use the same compat library, in my case appcompat-v7.
It is possible to exclude this library for each dependency
compile ('com.github......'){
exclude group: 'com.android.support', module: 'appcompat-v7'
}
But I need to do this in for each dependency
Another way is to use such expression
configurations {
compile.exclude module: 'appcompat-v7'
}
This works, but even If declare this library explicitly it is ignored compile 'com.android.support:appcompat-v7:+'
All what I need it is to include this library only once for the whole app, because if compile without exclude it will show a lot of errors like has been already defined.
Maybe there is an easier way to get this working. I would be grateful for any help, thanks.
We use a provided configuration in gradle (so that when we gradle:eclipse, the packages are included, but are not included when compiled into a jar, as these jars are expected to be provided at runtime). This configuration looks like the following:
configurations {
provided {
dependencies.all {dep ->
configurations.default.exclude group: dep.group, module:dep.name
}
}
compile.extendsFrom provided
}
This allows us to include dependencies as follows:
dependencies {
compile("org.scala-lang:scala-library:2.11.7")
compile("org.scala-lang:scala-compiler:2.11.7")
provided("org.apache.spark:spark-core_2_11:2.0.0")
}
Try creating a configuration which contains all dependencies where you want to exclude appcompat-v7, and then extend compile from this new configuration.

I've following dependency added in build.gradle file.
compile 'com.aerisweather:aeris-maps-lib:2.0.0#aar'
It is from
https://oss.sonatype.org/content/repositories/comaerisweather-1027/com/aerisweather/aeris-maps-lib/2.0.0/
If you the see artifacts from following URL, It has android support v7 library classes.
https://oss.sonatype.org/#nexus-search;quick~aerisweather
I want to exclude that package when running/packaging the application. I'm unable to run/package the app due to duplicate class error.
I've tried adding configurations like this,
configurations {
all*.exclude group: 'com.android.support', module: 'appcompat-v7'
}
But this excludes it from entire project which leads me to many errors.
I've tried everything but still getting following error.
Error:Execution failed for task ':transformClassesWithJarMergingForDebug'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v7/appcompat/R$anim.class
This library has also as dependency support-v4 and mediarouter-v7.
You need to exclude them all from aeris-maps-lib and include as your own dependency.
def supportLibraryVersion = '25.0.1'
dependencies {
compile "com.android.support:support-v4:${supportLibraryVersion}"
compile "com.android.support:support-annotations:${supportLibraryVersion}"
compile "com.android.support:appcompat-v7:${supportLibraryVersion}"
//... other deps
compile ('com.aerisweather:aeris-maps-lib:2.0.0#aar', {
exclude group: 'com.android.support', module: 'support-v4'
exclude group: 'com.android.support', module: 'appcompat-v7'
exclude group: 'com.android.support', module: 'mediarouter-v7'
})
}
PS.
aeris-maps-lib has also com.google.android.gms:play-services dependency, which is the whole Play Services package (it's large) and you will need to enable MultiDex or shrink code with proguard.
not a direct answer, but an advice.
The exclusion feature provided by gradle (exclude method invocation) doesn't work for contents inside local aar files as those contents aren't defined by dependency management and hence aren't recognised by the same.
As far as the dependency resolution is concerned, the aar file is an individual unit (including all the resources/classes within). So the file needs to be built in a way which doesn't include those entries; Or if the file is not built by you, you can unpack and omit the files in question and repack.
While there may be hackish ways to drop certain files using gradle (I couldn't find any reliable one yet), where we could possibly hook into some intermediate build steps and get rid of the files; but the generally advised best practise is to avoid packaging publicly available dependencies into the aar/jar to avoid duplicate entry issues and keep the aar/jar size smaller.
I see that I can specify gradle dependencies like this:
dependencies {
compile 'com.fasterxml.jackson.core:jackson-annotations:2.8.1'
compile 'com.fasterxml.jackson.core:jackson-core:2.8.1'
compile 'com.fasterxml.jackson.core:jackson-databind:2.8.1'
}
but also like this:
dependencies {
compile(
'com.fasterxml.jackson.core:jackson-annotations:2.8.1',
'com.fasterxml.jackson.core:jackson-core:2.8.1',
'com.fasterxml.jackson.core:jackson-databind:2.8.1'
)
}
This means that the compile configuration applies to a single element but also to a list of elements. Where do I find more details about the compile semantics? I'm referring also to details like the exclude module clause:
dependencies {
compile('org.simpleframework:simple-xml:2.7.1') {
exclude module: 'stax'
exclude module: 'stax-api'
exclude module: 'xpp3'
}
}
I've seen this page, but it doesn't contain this kind of details. Does Android Studio offer some kind of help to learn Gradle semantics?
Here is the DependencyHandler DSL documentation.
You can access Gradle API documentation from Android Studio like javadocs for Android framework APIs eg. using Quick Documentation shortcut (in default keymap Ctrl+Q or F1 on OS X).
You have to use Gradle all distribution. Eg. if you are using gradle wrapper it can be set in gradle/wrapper/gradle-wrapper.properties like that:
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
I am trying to remove the transitive dependencies from my Android project and for some reason exclude is not working when i try to remove a dependency from my particular dependency.
For example i want to remove support-annotations from my project
if i use
configurations {
all*.exclude group: 'com.android.support', module:'support-annotations'
}
The dependency gets excluded and from the dependency tree. i can see the dependency tree by using ./gradlew app:dependencies
But if i use
compile('com.android.support:support-v4:23.4.0')
{
exclude group: 'com.android.support', module:'support-annotations'
}
Then i still see the dependency in the dependency tree.
So my question is that why is it not working when i try to remove the dependency from a particular dependency ?
Update 1:
Also can anyone tell me what does the star (*) symbol next to dependency in the tree represent ?
Update 2
I am also using Fresco I tried the same thing with Fresco and exclude rule seems to work for it
Dependency Tree of Fresco
Dependency Tree when i exclude imagepipeline-base in Fresco
compile("com.facebook.fresco:fresco:0.9.0")
{
exclude group: 'com.facebook.fresco', module: 'imagepipeline-base'
}
As you can see the imagepipeline-base dependency gets excluded. So i don't know why this doesn't work for Android Support Annotations transitive dependency
So i have figured this out with the help of one of my friends. The reason why i was not able to remove support-annotation was because most of the other dependencies were using support-v4 as transitive dependency and those support-v4 also had their own copy of support-annotation.
Now there are 2 solutions to this
Solution 1:
exclude support-annotation from all the dependencies that containsupport-v4 as transitive dependency.
Solution 2:
exclude support-annotation only from my support-v4 dependency and remove support-v4 dependency from all other dependencies that have support-v4 as transitive dependency.
Note: Using one of the above approaches i was able to solve my problem and figure out how we can remove transitive dependencies when they are referenced from multiple dependencies.
And regarding the ( * ) symbol it means that the dependency tree is for that dependency is already shown. Instead of showing the whole tree for those dependencies again gradle shows ( * ) symbol with them.
Sample build.gradle file is available here
There is more graceful solution: you can use configueation.all block in your build.gradle file like in example below:
configurations.all {
exclude group: 'com.android.support', module: 'support-annotations'
}
It should exclude all transitive dependencies from all inner modules in your application.
In my Android project, I use a library that comes as a jar.
I include it in the dependencies section like so:
dependencies {
...
compile files('libs/thethirdpartylibrary.jar')
...
}
I also want to use the okhttp library, which I include like this:
compile ('com.squareup.okhttp:okhttp:2.7.5')
(This particular version of okhttp depends on okio 1.6.0.)
The problem is that the thirdparty jar library depends on okio v0.9.0 and what's worse, bundles it.
As a result, I get a dex conflict error at build time.
I was able to resolve this by manually removing okio from the jar file and this seems to work. But I'm wondering if there's a way to do this in gradle.
My question: Can I remove bundled, transitive ( <- I hope I'm using this word the right way) dependencies from an included jar during build-time with gradle?
Exclude the Group in the dependencies by using the below lines.
1.
configurations {
all*.exclude group: 'com.android.support', module: 'support-v4'
}
2.
dependencies {
compile 'com.android.support:support-v4:13.0.+'
compile ("com.xxx:xxx-commons:1.+") {
exclude group: 'junit', module: 'junit'
}
}
3.
configurations {
runtime.exclude group: "org.slf4j", module: "slf4j-log4j12"
}
Try this one.
For more detail
According to this discussion here https://groups.google.com/forum/#!topic/adt-dev/g1AiJM7PeVs, what you want to do is not possible.
The syntax suggested in the other answers is for "normal" Maven dependencies.
I need to prevent Android-Studio from exporting a certain shared library.
I´ve read that using the provided scope should work, but it seems that it not.Like this:
dependencies {
provided 'com.android.support:support-v4:21.0.3'
provided project(':DLlib')
}
My Module works as a plugin,I want to exclude support-v4 and DLlib library from the final apk!
Is there any other way to exclude dependencies from the build process to not get them into the final apk?
Try the 'exclude' keyword
compile('com.google.android.gms:play-services:6.+') {
exclude module: 'support-v4'
}
