我正在使用PropertyUtils.setSimpleProperty来动态调用我的setter方法，但是由于某些原因，我一直在出错。需要您的协助以找出根本原因。这是我的代码：

class FileDt {
    String reportName=null;
    String reportLocation=null;

    public String getReportName() {
        return reportName;
    }
    public void setReportName(String reportName) {
        this.reportName = reportName;
    }
    public String getReportLocation() {
        return reportLocation;
    }
    public void setReportLocation(String reportLocation) {
        this.reportLocation = reportLocation;
    }
}

class Foo {
    public static void main (String... args) {
        FileDt dt = newFileDt();
        // #1
        PropertyUtilsBean.setSimpleProperty(dt, "reportName", "abc.html");
        // #2
        PropertyUtilsBean.setSimpleProperty(dt, "reportLocation", "c://");
    }
}

这两种方法都抛出异常

1. 由以下原因引起：java.lang.NoSuchMethodException：属性'reportName'在org.apache.commons.beanutils.PropertyUtilsBean.setSimpleProperty（PropertyUtilsBean.java:2096）的类'FileDt'中没有setter方法

2. 由以下原因引起：java.lang.NoSuchMethodException：属性'reportLocation'在org.apache.commons.beanutils.PropertyUtilsBean.setSimpleProperty（PropertyUtilsBean.java:2096）的类'FileDt'中没有setter方法

我正在尝试通过 JNLP 通过命令行启动我的 Jenkins slave，以便我可以将命令放入任务调度程序中。但是，只有当我将 -secret 选项与 Jenkins 生成的密钥一起使用时，我才会面临身份验证问题。如果我使用与 Jenkins 相同的用户名密码传递 -auth 选项，则工作正常。

java -jar slave.jar -jnlpUrl http://<jenkins host>:<port>/jenkins/computer/<Slave name>/slave-agent.jnlp -secret <secret_key> -workDir "C:\Jenkins\Robot"

注意：我尝试执行的命令是从 Jenkins 页面复制的。

它给出以下错误：

 org.jenkinsci.remoting.engine.WorkDirManager initializeWorkDirINFO: Using C:\Jenkins\Robot\remoting as a remoting work directory Both error and output logs will be printed to C:\Jenkins\Robot\remoting Not use http_proxy property or environment variable which is invalid: unknown protocol: one.proxy.att.com Failing to obtain http://<host:port>/jenkins/computer/<job>/slave-agent.jnlp?encrypt=true

我正在尝试使用 Tomcat7-Maven-Plugin 为我的战争设置自动部署到 Tomcat。但是，它无法部署文件。从控制台消息来看，它似乎开始部署，但在 ard 2 MB 传输后被中断。所有重试都会发生同样的情况，最终失败。

$ mvn tomcat7:redeploy
