Answer 1

Had the same problem with a newly set up Android Studio 2.2.2, gradle wrapper 2.14.1. I loaded the project before i installed the needed android-23 library and installed java after Android Studio installation.

Error message in Android Studio 2.2.2:

Error:The specified Gradle distribution
'https://services.gradle.org/distributions/gradle-2.14.1-all.zip' does 
not appear to contain a Gradle distribution.

Error message in cmd:

projectfolder> gradlew
Exception in thread "main" java.lang.NullPointerException
at org.gradle.wrapper.BootstrapMainStarter.findLauncherJar(BootstrapMainStarter.java:34) 
at org.gradle.wrapper.BootstrapMainStarter.start(BootstrapMainStarter.java:25)
at org.gradle.wrapper.WrapperExecutor.execute(WrapperExecutor.java:129)
at org.gradle.wrapper.GradleWrapperMain.main(GradleWrapperMain.java:61)

When i used gradle from cmd however it worked

projectfolder> set PATH=%PATH%;C:\AndroidStudio2.0\gradle\gradle-2.14.1\bin\
projectfolder> set GRADLE_HOME=C:\AndroidStudio2.0\gradle\gradle-2.14.1\bin\
projectfolder> cd C:\projectfolder\
projectfolder> gradle
BUILD SUCCESSFUL

In cmd i see that the gradle versions and android sdk version were correct

C:\>set | find "JAVA_HOME"
JAVA_HOME=C:\Java\jdk1.8.0_111\

However in C:\Users\.AndroidStudio2.2\system\log\idea.log it said something else:

2016-11-29 16:04:10,597 [ 107684]   INFO - s.plugins.gradle.GradleManager - Instructing gradle to use java from C:/AndroidStudio2.0/jre

After messing up Android Studio config files i ended up reinstalling everything in correct order (Java, Android Studio, Project) and it worked.
