java.lang.UnsupportedClassVersionError: com/typesafe/config/ConfigException : Unsupported major.minor version 52.0

java.lang.UnsupportedClassVersionError: com/typesafe/config/ConfigException : Unsupported major.minor version 52.0

Java 8 has major version 52, which means if we run javac command from Java 8 installation, it will by default generate a class with major version 52. However, if we run class file in Java7, we will get "Unsupported major.minor version 52.0".

Solution :

There was a mis configuration in %JAVA_HOME%

• java -version java version "1.8.0_44"
• @echo %JAVA_HOME% C:\Program Files\Java\jdk1.7.0_75

To set the path temporary

• set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_44
• @echo %JAVA_HOME% C:\Program Files\Java\jdk1.8.0_44
