What is the error when building an Android project?

Question

Java

Good, I decided to learn how to develop for Android, but when building the project, I get the following error

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_79\bin\java.exe'' finished with non -zero exit value 1

There is nothing in the code, just Hello World
