Android Studio ignore --core-library flag

I have a project, which i want to configure on my computer.

On anothe computer it works, but with old version of Android Studio 0.4.0 whenever I use 0.5.2

The proble is that after I launch app it show error

Build script error, unsupported Gradle DSL method found: 'coreLibrary()'! Possible causes could be:
- you are using Gradle version where the method is absent - you didn't apply Gradle plugin which provides the method - or there is a mistake in a build script

But in order to make it work I have to use this flag! I already tried to enable it in the settings>Android compilers > "Add --core-library" flag, but it useless...

in the gradle i have next part of code:

    dexOptions {
    coreLibrary true;
}

This error showed only after activation this lines... Without them it don't work...

HOW SHOULD I FIX THIS? Maybe it is because of different versions.. if yes then how should I write to make it work?

After changing to coreLibrary = true It compilate Gradle fine BUt stille require after Run --core-library flag using.... But i already set it to true in settings...

It shows not almost the same error:

Error:Execution failed for task ':BusKg:preDexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    D:\Programms\Programms\adt-bundle-windows-x86_64-20131030\sdk\build-tools\android-4.4\dx.bat --dex --output D:\Android2\BUS.kg\marshrutka\BusKg\build\pre-dexed\debug\annotations-api-6.0.26-27e56569b50edbdd453f9bc0e568cde1fbfa621b.jar C:\Users\Viacheslav\.gradle\caches\modules-2\files-2.1\org.apache.tomcat\annotations-api\6.0.26\50aeafa144ed17913ed44d18ac61afd505a9e3e\annotations-api-6.0.26.jar
Error Code:
    1
Output:
    trouble processing "javax/xml/ws/WebServiceRef.class":
    Ill-advised or mistaken usage of a core class (java.* or javax.*)
    when not building a core library.
    This is often due to inadvertently including a core library file
    in your application's project, when using an IDE (such as
    Eclipse). If you are sure you're not intentionally defining a
    core class, then this is the most likely explanation of what's
    going on.
    However, you might actually be trying to define a class in a core
    namespace, the source of which you may have taken, for example,
    from a non-Android virtual machine project. This will most
    assuredly not work. At a minimum, it jeopardizes the
    compatibility of your app with future versions of the platform.
    It is also often of questionable legality.
    If you really intend to build a core library -- which is only
    appropriate as part of creating a full virtual machine
    distribution, as opposed to compiling an application -- then use
    the "--core-library" option to suppress this error message.
    If you go ahead and use "--core-library" but are in fact
    building an application, then be forewarned that your application
    will still fail to build or run, at some point. Please be
    prepared for angry customers who find, for example, that your
    application ceases to function once they upgrade their operating
    system. You will be to blame for this problem.
    If you are legitimately using some code that happens to be in a
    core package, then the easiest safe alternative you have is to
    repackage that code. That is, move the classes in question into
    your own package namespace. This means that they will never be in
    conflict with core system classes. JarJar is a tool that may help
    you in this endeavor. If you find that you cannot do this, then
    that is an indication that the path you are on will ultimately
    lead to pain, suffering, grief, and lamentation.
    1 error; aborting

Thanks in advance for any help...

How do I turn off lint on Android?

Configuring lint checking in Java or Kotlin To disable lint checking specifically for a class or method in your Android project, add the @SuppressLint annotation to that code. The following example shows how you can turn off lint checking for the NewApi issue in the onCreate method.

Is Android Studio heavy?

But it is even also heavy software which will suck your computer's ram. If your pc is not having a high configuration you can't run other applications like Google Chrome when your android studio is running. If you try to do so then your pc will start hanging. In this article, we will try our best to solve this problem.

Why does Android Studio take so long?

According to Android Studio's official system requirements, it takes at minimum 3 GB RAM to run smoothly. Honestly, its a lot and I believe that is the biggest cause of being it too slow all the time.

What is flavorDimensions?

Flavor Dimensions is a way to group flavors by a name. For now, we're using just a single group. Add the following line in your defaultConfig block: flavorDimensions "default" Now syncing the gradle would give you the following product flavors: Android Build Variants combine build types and product flavors.

project.tasks.withType(com.android.build.gradle.tasks.Dex) {
    additionalParameters=['--core-library']
}

does not work proper,and get the error:

Could not get unknown property 'com' for object of type com.android.build.gradle.AppExtension.

I solve the problem by adding this to android block.

dexOptions {
    preDexLibraries = false
    additionalParameters=['--core-library']
}

Hoping this is helpful to you!

In Android Studio 1.1.0, navigate to :

File --> Other Settings --> Default Settings --> Compilers --> Android Compilers

You will find the check-box to Add "--core-library" flag, but this does not seem to be working.

Instead editing the file app/build.gradle

Disabling pre-dexing inside android {} using

dexOptions {
    preDexLibraries = false
}

and modifying Dex task using

project.tasks.withType(com.android.build.gradle.tasks.Dex) {
    additionalParameters=['--core-library']
}

solves the problem.

Edit: Full contents of app/build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "appId"
        minSdkVersion 19
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    dexOptions {
        preDexLibraries = false
        javaMaxHeapSize "4g"
    }

    project.tasks.withType(com.android.build.gradle.tasks.Dex) {
        additionalParameters=['--core-library']
    }

    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/MANIFEST.MF'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE.txt'
        // more exclude files here if conflicts
    }
}
