Groovy 转换过程中出现常规错误：抓取葡萄下载失败的错误net.java.dev.jna

groovy 2.3.7版与gvm一起安装在mac上。我们支持一个公司代理，但maven在这里可以很好地用于java项目

尝试了以下方法

groovy groovySSHtest.groovy

这里的内容

@Grab(group='org.hidetake', module='groovy-ssh', version='1.0.1')
import org.hidetake.groovy.ssh.Ssh
def ssh = Ssh.newService()

ssh.remotes {
  mylaptop {
    host = '127.0.0.1'
    user = 'username'
    identity = new File('id_rsa')
  }
}

ssh.run {
  session(ssh.remotes.mylaptop) {
    //put 'example.war', '/webapps'
    execute 'pwd'
  }
}

并收到以下错误

已经尝试在.m2和.groovy中查找缓存，但什么也找不到

尝试设置用户/传递JAVA_选项，但没有成功。为ivy添加了以下调试设置

groovy -Divy.message.logger.level=4 groovySSHtest.groovy

使用代理用户/pass进行了尝试，出现了相同的错误

groovy -Divy.message.logger.level=4 -Dhttp.proxyUser=user -Dhttp.proxyPassword=pass groovySSHtest.groovy

…将在WFH在非公司代理网络上尝试此操作，以排除这种可能性。

这对我来说很有效，而且没有代理，这表明您需要这样做

我无法通过直接访问web重现这个问题。但是@Grap使用的是常春藤，这样做可能有助于进一步调试

groovy -Dhttp.proxyHost=proxyhost -Dhttp.proxyPort=8080 groovySSHtest.groovy
