Gradle sync fails with Dexguard plugin (Android Studio)

Question

I am having a bit of trouble trying to integrate dexguard to my android/gradle project.

• Dexguard: 5.5.32
• gradle: 2.2.1
• gradle-plugin: 1.3.0
• buildToolsVersion: 23.0.1

I get the following error when I apply plugin: 'dexguard':

Error:Unable to load class 'com.android.builder.SdkParser'

EDIT:

Here is my app's gradle file:

buildscript {
    repositories {
        flatDir { dirs '/usr/local/DexGuard5.5.32/lib' }
        jcenter()
    }
    dependencies {
        classpath ':dexguard:'
        classpath 'com.android.tools.build:gradle:1.3.0'
    }
}

apply plugin: 'com.android.application'
apply plugin: 'dexguard' //This, when uncommented produces the error

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile files('libs/commons-collections4-4.0.jar')
    compile files('libs/commons-codec-1.10.jar')
    compile files('libs/gson-2.3.1.jar')
    compile files('libs/jaxb2-maven-plugin:2.1.jar')
    compile project(':sdk')
    compile project(':zxing-lib')
}

        }
        app {
            applicationId "some.app.id2"
        }
    }
}

What are your thoughts ??

Answer 1

Your DexGuard plugin looks terribly outdated. The latest version, according to the GuardSquare website, is 7.0.22.

Upgrading is kind of mandatory, since version 7.x brought compatibility with gradle-plugin 1.3.x and build-tools 23.x.

Answer 2

Whats your Logcat Throws

Error:Unable to load class 'com.android.builder.SdkParser'

Cause

This problem is caused by android gradle plugin does not match for gradle version.

Courtesy

Actually you are using old version DexGuard5.5.32 .That's why have problem . Use latest version of Dexguard & latest SDK and gradle plugins .

DexGuard 6.0 released

This section takes you through the steps of hardening your application with DexGuard, from making sure the communication is secure, all the way to encrypting strings and classes.

And upgrade your tools.build:gradle version for better approach .

dependencies {
    classpath ':dexguard:'
    classpath 'com.android.tools.build:gradle:1.4.0-beta2'
}

Regards

You can set compileSdkVersion 23 instead of 22 .

Try this way .I hope it will helps you .
