android {
    compileSdkVersion 17
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 18
    }

    File signFile = rootProject.file('sign/keystore.properties')
    if (signFile.exists()) {
        Properties properties = new Properties()
        properties.load(new FileInputStream(signFile))
        signingConfigs {
            release {
                storeFile rootProject.file(properties['keystore'])
                storePassword properties['storePassword']
                keyAlias properties['keyAlias']
                keyPassword properties['keyPassword']
            }
        }
    }

    buildTypes {
        release {
            runProguard true
            zipAlign true
            proguardFile rootProject.file('proguard-rules.cfg')
            signingConfig signingConfigs.release
        }
        debug {
            runProguard false
            zipAlign true
        }
    }
}

我设法解决它添加这段代码，并与gradle构建:

android {
    ...
    signingConfigs {
        release {
            storeFile file("release.keystore")
            storePassword "******"
            keyAlias "******"
            keyPassword "******"
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }
}

这将生成一个已签名的发布apk文件。

我在Ubuntu14.04工作。 vim ~ /。Bashrc和add 出口ANDROID_KEYSTORE = 出口ANDROID_KEYALIAS =

然后是构建。它集。

    final Console console = System.console();
if (console != null) {

    // Building from console
    signingConfigs {
        release {
            storeFile file(System.getenv("KEYSTORE"))
            storePassword new String(System.console().readPassword("\n\$ Enter keystore password: "))
            keyAlias System.getenv("KEY_ALIAS")
            keyPassword new String(System.console().readPassword("\n\$ Enter key password: "))
        }
    }

} else {

    // Building from IDE's "Run" button
    signingConfigs {
        release {

        }
    }

}

如果您已经拥有密钥存储库文件，那么只需向构建命令中添加一些参数即可:

./gradlew assembleRelease \
 -Pandroid.injected.signing.store.file=$KEYFILE \
 -Pandroid.injected.signing.store.password=$STORE_PASSWORD \
 -Pandroid.injected.signing.key.alias=$KEY_ALIAS \
 -Pandroid.injected.signing.key.password=$KEY_PASSWORD

不需要对Android项目进行永久性更改。

如果您想避免在构建中硬编码您的密钥库和密码。gradle，你可以使用属性文件解释这里:处理签名配置与gradle

基本上:

1)创建一个myproject。属性文件在/home/[username]/。签名内容如下:

keystore=[path to]\release.keystore
keystore.password=*********
keyAlias=***********
keyPassword=********

2)创建gradle。属性文件(可能在你的项目目录的根目录)的内容:

MyProject.properties=/home/[username]/.signing/myproject.properties

3)在你的构建中参考它。这样Gradle:

    if(project.hasProperty("MyProject.properties")
        && new File(project.property("MyProject.properties")).exists()) {

    Properties props = new Properties()
    props.load(new FileInputStream(file(project.property("MyProject.properties"))))

    signingConfigs {
        release {
            storeFile file(props['keystore'])
            storePassword props['keystore.password']
            keyAlias props['keyAlias']
            keyPassword props['keyPassword']
        }
    }
}

我有几个问题，我把下面的行放在错误的地方:

signingConfigs {
    release {
        // We can leave these in environment variables
        storeFile file("d:\\Fejlesztés\\******.keystore")
        keyAlias "mykey"

        // These two lines make gradle believe that the signingConfigs
        // section is complete. Without them, tasks like installRelease
        // will not be available!
        storePassword "*****"
        keyPassword "******"
    }
}

确保你把signingConfigs部分放在了android部分:

android
{
    ....
    signingConfigs {
        release {
          ...
        }
    }
}

而不是

android
{
    ....
}

signingConfigs {
   release {
        ...
   }
}

很容易犯这个错误。
