错误:任务“:app:packageRelease"执行失败.>无法计算/../AndroidStudioProjects/../classes.jar 的哈希值

2022-01-13 00:00:00 android gradle android-gradle-plugin build.gradle java

我正在尝试在 Android 应用上进行发布"构建，但我不断收到以下错误:

I'm trying to do a 'release' build on an Android app and I keep on getting this error of:

无法计算/../AndroidStudioProjects/../classes.jar 的哈希

Unable to compute hash of /../AndroidStudioProjects/../classes.jar

然后，当我查看classes.jar"的目录时，该文件不存在.我是否必须使用 gradle 任务自己创建此文件?

And then when I look into that directory for 'classes.jar' the file isn't there. Do I have to create this file myself with a gradle task?

这里的 proguard 发生了一些事情，但除了无法计算哈希......"之外，它没有提供太多有用的信息.

There's something going on with proguard here but it's not giving much useful information other than 'Unable to compute hash...."

这是我的 gradle.build 文件:

Here's my gradle.build file:

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"
    defaultConfig {
        applicationId "com.example"
        minSdkVersion 11
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        debug {
            buildConfigField "String", "SERVER_URL", '"http://10.0.2.2:3000"'
        }
        release {
            buildConfigField "String", "SERVER_URL", '"https://example.com"'
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debugRelease {
            buildConfigField "String", "SERVER_URL", '"https://example.com"'
            debuggable true
            jniDebuggable false
            renderscriptDebuggable false
            minifyEnabled false
            zipAlignEnabled true
        }
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.android.support:recyclerview-v7:22.1.1'
    compile 'com.android.support:cardview-v7:22.1.1'
    compile 'com.google.android.gms:play-services-gcm:7.5.0'
}

如果有人可以帮助我调试这个问题，那就太好了.

If someone could help me debug this issue that'd be great.

推荐答案

我发现问题了:

为您的项目打开 proguard-rules.pro 并将其添加到底部:

Open up the proguard-rules.pro for your project and add this to the bottom:

-dontwarn java.nio.file.Files
-dontwarn java.nio.file.Path
-dontwarn java.nio.file.OpenOption
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

基本上我是如何解决这个问题的，我试图在发布"模式下运行我的应用程序，但遇到了一堆类似于这个人的错误:https://github.com/square/okio/issues/144

Basically how I solved it was this I tried to run my app in 'release' mode and got a bunch of errors similar to this guy here: https://github.com/square/okio/issues/144

我几乎按照他说的做了.

I pretty much followed what he said and fixed it.

希望这可以帮助其他人生成他们的 APK！

Hope this can help others with generating their APK's!
