The "Java: command not found" error occurs when building dev container from the Remote Project

Problem

When using the dev container Remote Project scenario,

the following error could occur:

Executing "java -version" command…
bash: line 1: java: command not found
Process exited with non-zero code 127

Resolution

As mentioned in our documentation Java 17+ is necessary to be installed on the Remote server where the Docker Engine is running.

• If Java is not installed on the remote server, install it, for example, using this instruction or via the package manager (apt install openjdk-17-jdk openjdk-17-jre for Ubuntu).

• If Java is installed, try to perform the following workarounds:

  • if Java is newer than 17, try to install Java 17 instead;
  • create a symlink for java command in /usr/local/bin.

Note that the IDE executes the commands on the remote server via the non-interactive non-login shell. The .bashrc, .profile, and other similar files will not affect the command execution.
