Android Studio Failed to Create MD5 hash for file

Question

I am building an Android project with a small team.

After implementing Facebook's Login system, I am no longer able to run my project, although it will build without problems.

The error: Error:Execution failed for task ':app:compileDebugJavaWithJavac'.

Failed to create MD5 hash for file 'C:\\Users\\me\\folder\\app\\src\\main\\java\\com\\team\\app\\httpclient-4.5.3.jar'.

If I go to my build.gradle module:app, I can see the line:

compile files('src/main/java/com/folder/app/httpclient-4.5.3.jar')

If I comment this out, the next compile line fails to make an MD5 hash.

I was able to run it, so I don't think its my path variable or JDK. I reinstalled JDK1.8. I have tried using the Android default JDK. I have added every path I could think of to my EnvVar.

After reading the other 10 SO articles about the same thing, I have made 0 ground.

Below is the full gradle file, but with naming details removed.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    defaultConfig {
        applicationId "com.our.app"

        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    }
}

    compile fileTree(include: ['*.jar'], dir: 'libs')

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'

        def requested = details.requested
        if(requested.group == 'com.android.support'){
            if(!requested.name.startsWith("multidex")){
                details.useVersion '25.3.0'
            }
        }
    }
}

Again, I am not trying to ask the same question over and over on here, but I have yet to find a solution to my problem.

Thanks in advance for any help you can provide. If I made some posting mistakes, please correct me so that I can draw the best attention to this post and not a bunch of people screaming about format.

Answer 1

    compile 'com.facebook.android:facebook-android-sdk:4.22.0'

Try to compile like this. I don't know whether this will work or not. But give it a try. Also, try to group compile dependencies together.

Answer 2

I had several building issues on my desktop, and the errors varried. Sometimes md5 errors, and sometimes errors in my build folder.

My solution was to disable my Anti-Virus, and that worked out pretty well. I was using Bitdefender on Windows.
