使用“进程”在共享库Jenkins管道中执行CURL

Question

我在Jenkins管道的共享库中有一个方法。其想法是使用此库并将文件上载到远程主机。该库导入到单例库中。

import com.package.jobutil.UploadFile

def uploadFunc() {
 def uploader = new UploadFile(this)
 withCredentials ([usernamePassword(credentialsId: 'user', userNameVariable: 'username', passwordVariable:'password)]) {
  uploader.uploadArtifact("${username}", "${password}", file.txt, location)
 }
}

def call() {
 uploadFunc()
}

实例化的类如下所示：

class UploadFile {
   def steps

   UploadFile (steps) {
     this.steps = steps
   }

   pulic uploadArtifct (String user, String password, String file, String location) {
   Process proc
   def cred = "${user}:${pass}"
   def cmd = ["curl", "-v", "-u", cred, "--upload-file", file, location]
   steps.println "CURL: ${cmd}"

   proc = cmd.execute()
  }
}

尽管我在日志中看到了println行。我看不到正在执行curl命令。是否有我缺少的不调用cmd的东西。执行才能工作？

编辑

当我在库中直接使用curl时，它可以工作。

pulic uploadArtifct (String user, String password, String file, String 
  location) {
  def cred = "${user}:${password}"
  def cmd = "curl -v -u ${cred} --upload-file ${file} ${nexusLocation}/${file}"
  try {

  steps.sh cmd
  } catch (Exception e) {
    throw new RuntimeExceptipon("Cannot execute curl, exception: [${e.getClass().getName()} - '${e.getMessage()}']")
   }
  }

但是，当尝试使用Process时，它不起作用。

pulic uploadArtifct (String user, String password, String file, String 
  location) {
  def cred = "${user}:${password}"
  def cmd = ["curl", "-v", "-u", cred, "--upload-file", ${file}, ${location}]
  try {
   def sout = new StringBuffer(), serr = new StringBuffer()
   def proc = cmd.execute()
   proc.consumeProcessOutput(sout, serr)
   proc.waitForOrKill(1000)
   println sout
  } catch (Exception e) {
    throw new RuntimeExceptipon("Cannot execute curl, exception: [${e.getClass().getName()} - '${e.getMessage()}']")
   }
  }

我得到的例外是：

java.lang.RuntimeException: Cannot execute curl, exception: [groovy.lang.MissingMethodException - 'No signature of method: java.lang.String.div() is applicable for argument types: (org.codehaus.groovy.runtime.GStringImpl) values: [file.txt]

正如这里所解释的，您需要捕获stdout/stderr来查看任何内容。

至少：

def outputStream = new StringBuffer();
proc.waitForProcessOutput(outputStream, System.err)
//proc.waitForProcessOutput(System.out, System.err)

或者，如本要点所述：

def sout = new StringBuffer(), serr = new StringBuffer()
def proc = cmd.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
println sout

阻塞调用的一个示例是：

println new ProcessBuilder( 'sh', '-c', 'du -h --max-depth=1 /var/foo/bar/folder\\ with\\ spaces | sort -hr').redirectErrorStream(true).start().text

def cmd = ["curl", "-v", "-u", cred, "--upload-file", ${file}, ${location}/${file}]
No signature of method: java.lang.String.div() is applicable for argument types: (org.codehaus.groovy.runtime.GStringImpl) values: [file.txt]

“${location}/${file}”中的“/”被解释为“/（div）操作，而不是字符串。

尝试使用curl命令参数：

${location}+"/"+${file}

正如您在随后的问题中指出的，all路径需要在双引号之间。
