Your IDE uses JDK, which stands for Java Development Kit (probably a bundled one). The key work here is development, i.e. JDK contains tools for developers, most notable a Java compiler, javac.

But it looks like your console is set up to use JRE, which is Java Runtime Environment. It's purpose is only running Java programs, but not compiling them, so, javac is not bundled in JRE.

Check if the javac is in yourt PATH by running javac -version from the console:

$ javac -version
javac 1.8.0_222

If it fails, add the JDK, not the JRE to the PATH or set it in JAVA_HOME environment variable. There are literaly dozens of articles in the Internet about Java, PATH and JAVA_HOME.

thanks dear, but i have done the environment variable correctly and when i type javac -version gave me java 1.8.0_111 – Abd Al Rahman Sep 05 '19 at 08:55
Thanks, was running a `JRE` only without `JDK`, aparrently thiught I had installed the JDK, now that works, On linux, run the command `sudo apt install openjdk-8-jdk-headless` and it auto installs the `JDK` for your system, change the version as u need – Jose Mhlanga Aug 20 '21 at 20:05

No compiler is provided in this environment, although I can build other project
