Why am I getting “Received fatal alert: protocol_version” or “peer not authenticated” from Maven Central?

Solution 1: configure Java 7

It is need to enable TLS 1.2 protocol with Java property in the command line

mvn -Dhttps.protocols=TLSv1.2 install

install is just an example of a goal

The same error for ant can be solved by this way

java -Dhttps.protocols=TLSv1.2 -cp %ANT_HOME%/lib/ant-launcher.jar org.apache.tools.ant.launch.Launcher

Solution 2: use Java 7 with Oracle Advanced Support

Also problem can be solved by updating the Java 7 version. But the last available version (7u80) doesn’t fix the problem. It is need to use an update provided with Oracle Advanced Support (formerly known as Java for Business).

Solution 3: use Java 8 or above instead

Configure $JAVA_HOME to point to Java 8.
