java - Tomcat7 maven 插件-处理请求时捕获 I/O 异常 (java.net.SocketException) : Broken pipe

Question

我一直在尝试使用 mvn tomcat7:deploy 命令部署我的 WAR 文件，但我遇到了管道损坏错误。我正在使用 Ubuntu。这是所需的文件。

这是 POM.xml

  <plugins>
        <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.0</version>
            <configuration>
                    <url>http://localhost:8080/manager/text</url>
                    <server>TomcatServer</server>
                    <path>/helloworld</path>
            </configuration>
        </plugin>
    </plugins>

我的/conf/settings.xml for tomcat有

<server>
    <id>TomcatServer</id>
    <username>maven</username>
    <password>maven</password>

和tomcatusers.xml如下

  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <role rolename="admin"/>
  <user username="maven" password="maven" roles="admin,managerscript,manager-gui"/>

使用以下命令进行部署

mvn tomcat7:deploy

我得到这些错误

我一直在寻找一段时间，但无法解决这个问题。

Answer 1

在您的 tomcatusers.xml 中，对于您具有角色“managerscript”的用户 maven，将其更改为 manager-script。此外，如果您从除 tomcat 所在的其他机器上运行 maven，请使用机器的 ip 地址并确保端口 8080 已打开以进行通信。
