Why am I getting "Error: Could not find or load main class org.apache.tools.ant.launch.Launcher" on Red Hat Enterprise Linux 6?
Issue
- Why does Java applications give an error Error: Could not find or load main class org.apache.tools.ant.launch.Launcher on RHEL 6?
- Ant doesn't not run with Java 8.
# ant -version
Error: Could not find or load main class org.apache.tools.ant.launch.Launcher
# ant --execdebug
