build gradle失败，带有“无方法签名…适用于参数类型：（java.lang.String）值”

Question

我有4个gradle构建文件：当我在android studio中构建时，我经常出现以下错误：

没有方法的签名：org.gradle.model.ModelMap.getDefaultProguardFile（）适用于参数类型：（java.lang.String）值：[proguard android.txt]

请：有人能帮我理解为什么我总是以下错误：

没有方法的签名：org.gradle.model.ModelMap.getDefaultProguardFile（）适用于参数类型：（java.lang.String）值：[proguard android.txt]

Answer 1

为我添加一个带有

jar {
    manifest {
        attributes 'Main-Class': com.package.to.main.Class
    }
}

帮助。

请参见此处：使用Gradle创建可运行JAR

Answer 2

Gradle不包括getDefaultProguardFile（），因为默认情况下它没有任何版本的ProGuard配置。

您可以使用将行从proguard android.txt移动到proguard rules.pro，然后更改此行：

proguardFiles.add(file('proguard-android.txt'))
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

为此：

proguardFiles.add(file('proguard-rules.pro'))
