Execute a Command

To execute a command at the command line, add the following to your build file:

@BuildCommand
public void startServer() throws Exception {
    new ExecOperation()
            .fromProject(this)
            .onWindows("cmd", "/c", "start.bat", "-p", "8080")
            .onUnix("./start.sh", "--port", "8080")
            .execute();
}

Exit Value

Use the failOnExit function to specify whether a command non-zero exit value (status) constitutes a failure.

@BuildCommand
public void startServer() throws Exception {
    new ExecOperation()
            .fromProject(this)
            .onWindows("cmd", "/c", "stop.bat")
            .onUnix("./stop.sh")
            .failOneExit(false)
            .execute();
}

Work Directory

You can also specify the work directory:

@BuildCommand
public void startServer() throws Exception {
    new ExecOperation()
            .fromProject(this)
            .command("touch", "foo.txt")
            .workDir(System.getProperty("java.io.tmpdir"))
            .execute();
}

Please check the ExecOperation documentation for all available configuration options.
