zipalign.exe'' finished with non-zero exit value

I'm a student programmer and I'm continuing an Android project that has been previously started by other students before me. My problem is that I'm getting an error when I try to execute the Android app inside Android Studio. You can see the error message below. The compilation must have worked for the other students since I have an apk file. What's wrong with zipalign?

:app:zipalignDebug FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:zipalignDebug'.
> Process 'command 'X:Sdk Android Studiobuild-tools21.1.2zipalign.exe''
finished with non-zero exit value -1073741502


My build.gradle:

apply plugin: 'com.android.application'

android {
compileSdkVersion 21
buildToolsVersion "21.1.2"

defaultConfig {
applicationId "csf.dfc.friendtracker"
minSdkVersion 15
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile files('libs/guava-18.0.jar')
compile files('libs/Pubnub-Android-3.7.2.jar')
compile files('libs/mysql-connector-java-5.1.34-bin.jar')
}


EDIT:
I haven't found the cause of the error but I added all the project objects in a new one and the error disappeared.

Remove the apk file in the Deploy directory and the export worked fine then.

I realized this happen when you have the directory "..appbuildoutputsapk" open in your Windows Explorer. You just need to close it and rebuild the project.

This happened to me too, when I tried to generate the apk in the following path:

C:usersdesktop


Change your signed generated apk destination path used to generate to the following:

<your project path>appbuildoutputsapk


Example:

E:androidStudioCountDownTimerappbuildoutputsapk
