通过 Jenkins(使用 Maven)在 Tomcat7 上部署 war 时，java.net.socketexception 连接由对等套接字写入错误重置

Question

我正在尝试通过 Jenkins 在 tomcat7 上部署一个基于 maven 的 Web 项目。当我尝试从我的命令提示符执行 Maven 目标“mvn tomcat7:deploy”时，它工作正常并将应用程序部署到正在运行的 tomcat7 实例上。现在我在 Jenkins 上为相同的项目设置了一个作业并收到套接字错误。下面是我的代码和来自 Jenkins 控制台的堆栈跟踪。

POM.xml 中的条目

<plugin>
        <groupId>org.apache.tomcat.maven</groupId>
        <artifactId>tomcat7-maven-plugin</artifactId>
        <version>2.2</version>
        <configuration>
            <url>http://localhost:8080/manager/text</url>
            <server>Tomcat7Server</server>
            <path>/ElecnorMPR</path>
        </configuration>
    </plugin>

Apache Maven 设置.xml

<server>
  <id>Tomcat7Server</id>
  <username>tomcat</username>
  <password>tomcat</password>
</server>

已在 tomcat-user.xml 中定义用户。

我在 heroku 中部署 war 时也遇到了这个错误。但是重新部署后就成功部署了
