Maven version I installed is maven 3.3.3
My java version is:
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)
echo $PATH returns:
/Library/Maven/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin
How to solve the problem of Maven?

$JAVA_HOME should be pointing to 1.8.0_65 as in your case.
If you want it to permanently change the value of JAVA_HOME, you will have to add the command to your ~/.profile file. Below are instructions on how to accomplish this instead:
Open up Terminal.app (Applications → Utilities → Terminal)
Type:
emacs .profile
Add this to the end of the .profile file:
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home
export JAVA_HOME;
Note that JAVA_HOME should be the path of your JDK directory.
Save and exit emacs (ctrl-x, ctrl-s; ctrl-x, ctrl-c)
Open a new Terminal window (cmd-n) and type:
$JAVA_HOME/bin/java -version

UnsupportedClassVersionError on running play application with JDK 1.7

Just now started learning Play framework for my project requirement and my project only build on JDK 1.7 so I have downloaded Play 2.3.9 version and created a sample project by typing activator new. Then moved into the sample project directory and executed activator run. Then I see JDk incompatible exceptions. Where I have to make the changes to handle this?

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

52 = Java 8, 51 = Java 7.. On com.typesafe.config.ConfigException; so you have a too new library.

Description :
Java SE 8 = 52
Java SE 7 = 51
Java SE 6.0 = 50
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 JRE 7, 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_45"
javac -version javac 1.8.0_45
#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_45
#echo %JAVA_HOME% C:\Program Files\Java\jdk1.8.0_45

ConfigException occurs because from version 1.3.0, com.typesafe.config library is only compatible with JDK8; see README. You need to downgrade the library version. Use
"com.typesafe" % "config" % "1.2.1"

Although it seemed I was using the same version for java and javac:
java -version java version "1.8.0_51"
javac -version javac 1.8.0_51
My problem was (Linux Mint 17.1) that I had installed oracle-java7 and oracle-java8 so somewhere there must be a misconfiguration.
I uninstalled oracle-java7 and everything worked fine to me.

Faced similar issue, resolved by changing version
//addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.0")
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.9")
With above changes below exception got resolved (note: system has java 7)
Exception got with higher version:

Indeed what #cib is saying solves my problem.
Just modify the file plugins.sbt in my projet directory.
Change the line :
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.2")
to:
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.9")
and you'll not get any errors doing activator run again.

error install jigsaw on linux with java

I'm trying to install Jigsaw on Linux. I have installed on my machine JDK.here is the message of java -version:

I followed your instructions but when I execute install.sh I receive:

So I choose the manual way exporting CLASSPATH but when I execute java Install here it is the message
