Android Studio 更新 - 无法解析 com.android.databinding

Question

我最近更新了我的JAVA 到1.8 版本，也更新了android studio 和gradle 插件。更新后，我的一个模块(即 facebook 模块)build.gradle 文件在编译我的项目时出现以下错误:

我的项目级 build.gradle 如下所示:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0-beta4'
        classpath 'com.google.gms:google-services:2.0.0-alpha6'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

在 facebook 模块 build.gradle 文件中也有一些符号未找到错误，如无法解析符号 'GradleScriptException' 和无法解析符号 'MavenDeployment'。 facebook buil.gradle 的完整代码是:

apply plugin: 'com.android.library'

repositories {
    mavenCentral()
}

project.group = 'com.facebook.android'

dependencies {
    // Facbook Dependancies
    testCompile 'com.android.support:appcompat-v7:23.0.1'

uploadArchives.dependsOn(setVersion)

    source = android.sourceSets.main.java.srcDirs
    classpath += project.files(android.getBootClasspath().join(File.pathSeparator))
    // JDK 1.8 is more strict then 1.7. Have JDK 1.8 behave like 1.7 for javadoc generation
    if (org.gradle.internal.jvm.Jvm.current().getJavaVersion() == JavaVersion.VERSION_1_8) {
        options.addStringOption('Xdoclint:none', '-quiet')

    classifier = 'javadoc'
    from androidJavadocs.destinationDir
}

task androidSourcesJar(type: Jar) {
    classifier = 'sources'
    from android.sourceSets.main.java.sourceFiles
}

artifacts {
    archives androidSourcesJar
    archives androidJavadocsJar
}

afterEvaluate {
    androidJavadocs.classpath += project.android.libraryVariants.toList().first().javaCompile.classpath
}

点击Upgrade plugin and sync project 不会执行任何操作。

我已经按照各种来源的建议尝试了“使缓存无效并重新启动”，但没有奏效。我已经在我的项目 build.gradle 中提到了最新版本的 gradle 插件。

我已经经历了Gradle DSL Method not found: testCompile() 但它不能解决我的问题。

我应该怎么做才能消除这个编译错误？

TIA

编辑 1: 我按照 sm4 的建议进行了更改，此 DSL 方法未找到错误消失了，但现在它无法编译并出现以下错误:

Answer 1

def powerMockVersion = '1.6.1'
testCompile "org.powermock:powermock-module-junit4:$powerMockVersion" testCompile "org.powermock:powermock-module-junit4-rule:$powerMockVersion" testCompile "org.powermock:powermock-classloading-xstream:$powerMockVersion" androidTestCompile 'com.google.dexmaker:dexmaker:1.2'
testCompile "org.powermock:powermock-api-mockito:$powerMockVersion" androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.2'
// Connected Tests
androidTestCompile 'org.mockito:mockito-core:1.10.19'

testCompile 实际上是对方法的调用。因为您在一行中有多个 testCompile，所以它被视为对具有许多参数的方法的调用。不存在这种方法。

每行只保留一个定义，它应该可以工作:

testCompile "org.powermock:powermock-module-junit4:$powerMockVersion"
testCompile "org.powermock:powermock-module-junit4-rule:$powerMockVersion"
testCompile "org.powermock:powermock-classloading-xstream:$powerMockVersion"
androidTestCompile 'com.google.dexmaker:dexmaker:1.2'
testCompile "org.powermock:powermock-api-mockito:$powerMockVersion"
androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.2'
