Question

某处似乎有内存泄漏。

在IntelliJ中设置项目并使用Gradle包装器时：

./gradlew assembleDebug --debug

大约5分钟后我得到以下信息：

我正在使用Scala 2.9.3但遇到与2.10.x相同的问题。

这是我的build.gradle。

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}

apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 19
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'

    // Scala.
    compile 'org.scala-lang:scala-library:2.9.3',
            'org.scala-lang:scala-compiler:2.9.3'
}

是否有人使用Gradle + Scala成功编译Android项目。

谢谢！

看起来你正试图dex整个Scala库。这里有2个选项：

尝试增加堆大小。您可以在this group中了解如何执行此操作。但是，这不会解决构建时间问题。
尝试在实际dexing之前使用proguard。

将Scala与Gradle一起用于Android项目
