Android proguard问题:path不能为null或为空字符串. path ='null' [英] Android proguard issue: path may not be null or empty string. path='null'

问题描述

设置之前，一切正常

minifyEnabled为真

minifyEnabled true

和

shrinkResources为真

shrinkResources true

设置这些值后，每当我运行项目时，都会出现此错误:

After setting these values, whenever i run project i get this error:

Information:Gradle tasks [:app:assembleProdRelease]
Error:path may not be null or empty string. path='null'
Information:BUILD FAILED
Information:Total time: 23.606 secs
Information:1 error
Information:0 warnings
Information:See complete output in console

此错误是什么意思 Error:path不能为null或为空字符串. path ='null' 这是build.gradle:

What does this error means Error:path may not be null or empty string. path='null' Here is build.gradle :

signingConfigs {
            release {
                storeFile file('/home/rishabh/Documents/dekhoJks/release.jks')
                storePassword "XXXXXXX"
                keyAlias "XXXXXXXX"
                keyPassword "XXXXXXXXX"
            }
        }
        buildTypes {
            release {
                minifyEnabled true
                //proguardFiles fileTree(dir: "proguard", include: ["*.pro"]).asList().toArray()
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
                shrinkResources true
                signingConfig signingConfigs.release
            }
        }

我试图将所有我可以放的东西放到proguard.pro中:

And i tried to put every single damn thing i can put in proguard.pro :

但是仍然无法运行我的应用程序.我要去哪里的任何帮助.

But still unable to run my app. Any help where i'm going wrong.

推荐答案

好了.只需替换您辛苦的签名配置即可:

Okay got the solution. Just replace your hard codded signing config:

release {
                storeFile file('/home/rishabh/Documents/dekhoJks/release.jks')
                storePassword "XXXXXXX"
                keyAlias "XXXXXXXX"
                keyPassword "XXXXXXXXX"
            }

，而不是创建一个单独的 signing.properties 文件:

and instead of that create separate signing.properties file :

STORE_FILE=/home/XXX/XXX/XXX
STORE_PASSWORD=XXXXXX
KEY_ALIAS=XXXXXXXX
KEY_PASSWORD=XXXXXXXXX

并在gradle中使用. 希望对您有帮助！

and use in your gradle. Hope it helps!!
