groovy – process.text的错误等价物？

You can get the entire output stream使用.text：

def process = "ls -l".execute()
println "Found text ${process.text}"

是否有一个简洁的等价物来获取错误流？

解决方法

你可以使用waitForProcessOutput,它有两个Appendables( docs here)

def process = "ls -l".execute()
def (output,error) = new StringWriter().with { o -> // For the output
  new StringWriter().with { e ->                     // For the error stream
    process.waitForProcessOutput( o,e )
    [ o,e ]*.toString()                             // Return them both
  }
}
// And print them out...
println "OUT: $output"
println "ERR: $error"
