Error in gradle build after updating Android Studio with log4j

android android-studio build dependencies build.gradle
17,905

Solution 1

Add this line to proguard-rules.pro

-keepattributes EnclosingMethod

This error may happen almost all classes which has InnerClasses, I think. (like support.v4 etc) for me.

I've tested on Android studio 2.2
(Not tested log4j. Tested support.v4 etc.)

build.gradle

compileSdkVersion 24
buildToolsVersion "24.0.2"
...
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
...
dependencies {
    ...
    compile 'com.android.support:support-v4:24.2.1'
}

getDefaultProguardFile('proguard-android-optimize.txt') also works.

Solution 2

I was also facing this same error. It was driving me crazy because the error count was >1K. And I was getting these errors on release build with proguard enabled.

After doing some digging I found that adding -keepattributes EnclosingMethod in your proguard-rules.pro file all these error will be gone.

    I hope i provided any important information

    If someone does know anything ... please help me! I cannot find anything in this "NEULAND"

    Sorry for the long question... Thanks for anyone who has made it up to here.

    I updated the dependencies to:

compile 'org.slf4j:slf4j-api:1.7.21'
compile 'org.slf4j:slf4j-log4j12:1.7.21'

    But nothing has changed. I still have about 500 build errors .... I deleted mindpipe as reference an coded it by myself ... Nothing happened!

    Opened a ticket: Issue 206867

    EDIT:

    After uninstall Android Studio 2.0 and install 1.5.1 again I get the following warning:

    Warning:Gradle version 2.10 is required. Current version is 2.8. If using the gradle wrapper, try editing the distributionUrl in C:\Sources\iRecyApps\iRecyMulco-1.0.1iOS\gradle\wrapper\gradle-wrapper.properties to gradle-2.10-all.zip

    So the gradle version was updated by 2...

    I informed myself about the current gradle version and it's 2.12

    I downloaded both and tried this:

    You need to change File > Settings > Builds,Execution,Deployment > Build Tools > Gradle >Gradle home path

    On Mac OS, change the path in Android Studio > Preferences > Builds,Execution,Deployment > Build Tools > Gradle >Gradle home

    Or set Use default gradle wrapper and edit Project\gradle\wrapper\gradle-wrapper.properties files field distributionUrl like this

    according to:

      Are you searching for a way to run the app even with this errors? Normally this errors are not relevant and if you disable instant run, the app will compile and run fine... With instant run enabled, I could not get my app working yet though...
