我们习惯于使用 maven ant 任务将我们的工件发送到我们的服务器，但现在这不再起作用了......我不知道发生了什么变化，当 maven 运行任务时，我们得到这个异常
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.8:run (scp-to-remote) on project quipark: An Ant BuildException has occured: com.jcraft.jsch.JSchException: Auth fail
[ERROR] around Ant part ...<scp trust="true" password="password" localFile="path_to_jar" remoteToFile="admin@192.168.3.240:/Users/admin/Public/dir" verbose="true"></scp>... @ 4:204 in /Users/admin/sviluppo/workspace/app/target/antrun/build-main.xml
如果我们使用钥匙孔选项而不是密码，它也不起作用。这很奇怪，因为我们可以使用相同的凭据毫无问题地进入服务器
这是插件的POM部分

${remoteToFile}取自我的Maven设置，就像admin@192.168.3.240：/Users/admin/Public/dir
这是异常的完整堆栈跟踪
