Question

我有一个项目，我想在我的计算机上配置。

在其他计算机上它可以工作，但是每当我使用0.5.2

时，都会使用旧版Android Studio 0.4.0

问题在于我启动应用后显示错误

构建脚本错误，找不到支持的Gradle DSL方法：'coreLibrary（）'！           可能的原因可能是：
           - 您正在使用没有方法的Gradle版本            - 您没有应用提供该方法的Gradle插件            - 或者构建脚本中存在错误

但为了使它工作，我必须使用这个标志！我已经尝试在设置＆gt; Android编译器＆gt;中启用它“添加--core-library”标志，但它没用......

在gradle中我有下一部分代码：

    dexOptions {
    coreLibrary true;
}

此错误仅在激活此行之后显示...如果没有它们，它将无效...

我该如何修复？也许是因为版本不同..如果是的话那么我应该如何写它才能使它工作？

更改为coreLibrary = true之后使用....运行--core-library标志后编译Gradle fine BUt stille require但是我已经在设置中将其设置为true ...

它显示的差异几乎不一样：

Error:Execution failed for task ':BusKg:preDexDebug'.

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.

Answer 1

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

无法正常工作，并收到错误：

无法为com.android.build.gradle.AppExtension类型的对象获取未知属性'com'。

我通过将其添加到android块来解决问题。

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

希望这对你有所帮助！

Answer 2

在Android Studio 1.1.0中，导航至：

档案 - ＆gt;其他设置 - ＆gt;默认设置 - ＆gt;编译器 - ＆gt; Android编译器

您将找到添加“--core-library”标志的复选框，但这似乎不起作用。

而是编辑文件app / build.gradle

使用

禁用android {}内的预删除

dexOptions {
    preDexLibraries = false
}

并使用

修改Dex task

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

解决了这个问题。

编辑： app / build.gradle的完整内容

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
    }
}

Answer 3

我认为我们无法通过--core-library启用dexOptions。

我们知道dexOptions委托给com.android.build.gradle.internal.dsl.DexOptions对象，该对象实现了com.android.builder.core.DexOptions。

从源代码中，我们知道它不支持--core-library。

来自Issue 79280: dexOptions in gradle plugin don't support coreLibrary

您可以通过
手动完成

禁用pre-dexing（这是因为如果我们允许添加额外的参数，我们的缓存会出现问题）

修改Dex任务以添加--core-library作为额外参数。

Answer 4

您好我有同样的问题，我通过选中/ Preferences / Compiler / Android Compilers中的“添加--core-library”框来解决它

Answer 5

我解决了这个问题！不幸的是我只是通过安装Android Studio 0.4.2版本来解决它....其他方法没有帮助...可能，稍后，最好为新版本的Android Studio配置项目。

Answer 6

您必须排除导致此问题的库。例如： -

compile('org.simpleframework:simple-xml:2.7.+'){
    exclude module: 'stax'
    exclude module: 'stax-api'
    exclude module: 'xpp3'
}

Answer 7

指定dexOptions值的语法不同;你需要一个等号：

dexOptions {
    coreLibrary = true;
}

Android Studio忽略--core-library标志
