Library already added: Gradle Build

I just updated my project with the new gradle build system.

Having tried several times, I always with the same error.

I have a project with many sub-library projects. They use support-library-v4, and my main project also uses it. After some searching, I found that I need to use the maven link:

compile 'com.android.support:support-v4:13.0.0' 

I added this (and left the jar in the libs folder for eclipse compatibility) but got the same error

 UNEXPECTED TOP-LEVEL EXCEPTION: java.lang.IllegalArgumentException: already added: Landroid/support/v4/app/ActivityCompatHoneycomb; at com.android.dx.dex.file.ClassDefsSection.add(ClassDefsSection.java:123) at com.android.dx.dex.file.DexFile.add(DexFile.java:163) at com.android.dx.command.dexer.Main.processClass(Main.java:490) at com.android.dx.command.dexer.Main.processFileBytes(Main.java:459) at com.android.dx.command.dexer.Main.access$400(Main.java:67) at com.android.dx.command.dexer.Main$1.processFileBytes(Main.java:398) at com.android.dx.cf.direct.ClassPathOpener.processArchive(ClassPathOpener.java:245) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:131) at com.android.dx.cf.direct.ClassPathOpener.process(ClassPathOpener.java:109) at com.android.dx.command.dexer.Main.processOne(Main.java:422) at com.android.dx.command.dexer.Main.processAllFiles(Main.java:333) at com.android.dx.command.dexer.Main.run(Main.java:209) at com.android.dx.command.dexer.Main.main(Main.java:174) at com.android.dx.command.Main.main(Main.java:91) 

I even tried deleting these libraries in the / libs folder, but no luck

I am using the latest version of gradle " classpath 'com.android.tools.build:gradle:0.5.4' " but no luck.

Hope someone has a better idea?

Here is my build script:

 buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.5.4' } } allprojects { repositories { mavenCentral() } } apply plugin: 'android' dependencies { repositories { mavenCentral() } compile project(':HoloGraphLibrary') compile project(':CardsUI') compile project(':Caldroid') compile project(':BetterPickers') compile project(':Crouton') compile project(':ShowcaseView') compile project(':AboutLibraries') compile project(':StyledDialogs') compile 'com.nineoldandroids:library:2.4.0' compile 'com.android.support:support-v4:13.0.0' compile 'joda-time:joda-time:2.2' compile files('libs/ActiveAndroid-3.3.jar') compile files('libs/crashlytics.jar') } android { compileSdkVersion 17 buildToolsVersion "17.0.0" defaultConfig { minSdkVersion 14 targetSdkVersion 17 } sourceSets { main { manifest.srcFile 'AndroidManifest.xml' java.srcDirs = ['src'] resources.srcDirs = ['src'] aidl.srcDirs = ['src'] renderscript.srcDirs = ['src'] res.srcDirs = ['res'] assets.srcDirs = ['assets'] } instrumentTest.setRoot('tests') } } 

and here is one of them - the script of one of my libraries:

 buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.5.4' } } apply plugin: 'android-library' dependencies { // compile fileTree(dir: 'libs', include: '*.jar') compile 'com.android.support:support-v4:13.0.0' compile 'joda-time:joda-time:2.2' } android { compileSdkVersion 17 buildToolsVersion "17.0.0" defaultConfig { minSdkVersion 8 targetSdkVersion 17 } sourceSets { main { manifest.srcFile 'AndroidManifest.xml' java.srcDirs = ['src'] resources.srcDirs = ['src'] aidl.srcDirs = ['src'] renderscript.srcDirs = ['src'] res.srcDirs = ['res'] assets.srcDirs = ['assets'] } instrumentTest.setRoot('tests') } }

Ok, now I feel a little stupid.

I just tried this one last time with gradle clean build and guess it works :)

So the trick with the maven repositories and the new clean worked for me.

Excuse for troubling. Thanks

Are you sure all your sub-libraries have a line

 compile fileTree(dir: 'libs', include: '*.jar') 

commented?
