When I'm trying to build my app it's building process is stopped showing the following message in logcat it's showing error
Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.

You are using the SNAPSHOT version :
compile 'org.lucasr.twowayview:core:1.0.0-SNAPSHOT#aar'
compile 'org.lucasr.twowayview:layouts:1.0.0-SNAPSHOT#aar'
and the STABLE version both at the same time
compile 'org.lucasr.twowayview:twowayview:0.1.4'
Try removing any of them. You should only use one at a time.

Build.Gradle (Module App ) unknown property

I have encountered this problem while syn of Gradle
This is the Code of build.gradle(Module app)
apply plugin: 'com.android.application'
android {

buildToolsVersion "25.0.3"
defaultConfig {
applicationId "ahmedchtn.smartschool"

}
}
}

compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'
testCompile 'junit:junit:4.12'
}
I have tried to deleted some lines of compile but I did not arrive to resolve the problem,

You have few typos in your file:
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.android.support:appcompat-v7:25.3.1'
You should not have line break after compile.
Typical structure of dependencies block is:
dependencies {
// production
compile 'group:name:version'
// for local tests
testCompile 'group:name:version'
// for tests on device / emulator
androidTestCompile 'group:name:version'
}
If you really want to have line break (I don't even know why) you have to explicitly add parentheses around dependency definition:
compile (
'com.github.bumptech.glide:glide:3.7.0'
)

Change it to this.
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:support-v4:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.google.code.gson:gson:2.6.2'
compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'
testCompile 'junit:junit:4.12'

not have problems with gradle process any error..
so have problems in ejecuttion application.. because my buttknife not working injection.
Maybe exist version so working fine with rxjava librarys ? or the version is really low
my version library compile 'com.jakewharton:butterknife:7.0.1'

It looks like you are not importing AnnotationProcessor.
Try this with latest versions:
compile 'com.jakewharton:butterknife:8.6.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.6.0'

I was also facing the same issue
after searching i found this solution
It is the duplicate issue

I am Suddenly getting Play-Service-app-indexing:10.0.1 error in gradle of android Studio

Error:(41, 13) Failed to resolve: com.google.android.gms:play-services-appindexing:10.0.1
Here is my build.gradle file of my project in Android Studio, the errors has came suddenly.

}

Referring to this post, you should remove
compile 'com.google.android.gms:play-services-appindexing:10.0.1'
since using the new library dependency (below) should be enough.
compile 'com.google.firebase:firebase-appindexing:10.0.0'
I copied the part of your gradle file for dependencies and encountered the same. After removing the duplicate (compile 'com.google.android.gms:play-services:10.0.1') and replacing the dependency as mentioned above, the build was successful.
dependencies {
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'
})
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.google.android.gms:play-services:10.0.1'
compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.android.support:appcompat-v7:25.1.1'
compile 'com.android.support:design:25.1.1'
compile 'com.google.firebase:firebase-appindexing:10.0.1'
testCompile 'junit:junit:4.12'
apk 'com.google.android.gms:play-services:10.0.1'
compile 'com.google.firebase:firebase-appindexing:10.0.1'
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:support-v4:25.1.1-beta1'
// Glide image library
compile 'com.github.bumptech.glide:glide:3.7.0'
}

You have
compile 'com.google.firebase:firebase-appindexing:10.0.0'
compile 'com.google.android.gms:play-services-appindexing:10.0.1'
Check if just one of them is necessary.
Also check changing firebase-appindexing to 10.0.1
