Groovy 执行 mvn 命令

Question

I'm writing groovy script and trying to execute following shell command using execute() method

"mvn clean install -f \{pom directory}\pom.xml".execute()

but got an error with following message

"Cannot run program "mvn": error=2, No such file or directory"

Of course, maven is already installed and the command works well on terminal....

I also tried with "sc -c" prefix.

"sh -c mvn clean install -f \<pom directory\pom.xml".execute()

But this does execute nothing and no error at all. it seems like the command just ignored.

So how should I execute maven install in groovy script?

On windows, mvn is not an exe-file but a command (mvn.cmd). I fixed the issue the following way:

def cmd = ""
if (System.properties['os.name'].toLowerCase().contains('windows')) {
    println "On Windows mvn is a CMD and not an EXE"
    cmd = "mvn.cmd wrapper:wrapper"
} else {
    println "Execute just the mvn executable on non Windows systems"
    cmd = "mvn wrapper:wrapper"
}
def process = cmd.execute(null, rootDir)
process.waitForProcessOutput((Appendable)System.out, System.err)
if (process.exitValue() != 0) {
    println "WARNING: Command '$cmd' exited with code: ${process.exitValue()}"
    println "WARNING: you can initialize the maven wrapper by yourself:}"
    println "WARNING: go to $rootDir and type in 'mvn wrapper:wrapper'}"
}
