I have a problem with my compiled Java application on Ubuntu. It throws UnsupportedClassVersionError
.
I am compiling with a higher JDK version than the one that is configured in my PATH to run Java:
$ javac -version
javac 1.7.0_147
$ java -version
java version "1.6.0_23"
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.2)
OpenJDK Client VM (build 20.0-b11, mixed mode, sharing)
How can I resolve this?
Run either of the following to locate where the location is of that
javac 1.7.0_147
being used as follows:
whereis javac
or
locate javac
or
find javac
Then once you found the directory, symbolically and forcefully link the bin contents to /usr/bin:
sudo ln -f -s [put location here]/bin/* /usr/bin
