android - 无法使用 Android Studio 1.2 和 Gradle 1.2.2 加载类 OutputFileTask

Question

升级到 Android Studio 1.2 后，我在尝试同步我的项目时遇到以下错误

Error:Unable to load class 'com.android.build.gradle.internal.tasks.OutputFileTask'. Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

这是我的gradle文件

apply plugin: 'com.android.library'
apply plugin: 'maven'
apply plugin: 'maven-publish'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    repositories {
        mavenCentral()
    }

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            consumerProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    lintOptions {
        abortOnError false
        checkReleaseBuilds false
    }

    packagingOptions {
        exclude 'META-INF/services/javax.annotation.processing.Processor'
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LGPL2.1'
    }
}


dependencies {
    compile 'com.android.support:support-v4:22.1.0'
    compile 'com.android.support:appcompat-v7:22.1.0'
}

task sourceJar(type: Jar) {
    classifier "source"
}



publishing {
    publications {

        repositories.maven {
            url repo
            credentials {
                username user
                password passwd
            }
        }

        maven(MavenPublication) {
            artifacts {
                groupId 'com.android'
                artifactId 'artefact-1'
                version '1'
                artifact artifactPath
            }
        }
    }

}

}

我认为可能还有另一个 gradle api 更改导致旧的东西不再工作。

如何解决问题以重新构建我的项目？

Answer 1

您在使用 dexguard 吗？我有一个旧的 dexguard 版本的问题。自从我更新到 6.1.19 就没有问题了。 (目前使用 AS 1.2.1 & Gradle 2.4 & 1.2.3)
