maven - 尝试将应用程序部署到tomcat7服务器时出错

Question

我正在尝试通过Eclipse Luna将Web应用程序部署到tomcat7，但出现此错误:

Uploading: http://localhost:8080/manager/text/deploy?path=%2Floja

[INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset

我也尝试将其部署到tomcat8，但出现了同样的错误。

在我的pom.xml中，我具有与此操作相关的配置:

  <build>
    <finalName>loja</finalName>
    <plugins>
        <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>TomcatServer</server>
                <path>/loja</path>
                <username>user001</username>
                <password>123</password>
           </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <configuration>
                <failOnMissingWebXml>false</failOnMissingWebXml>
            </configuration>
        </plugin>
    </plugins>
</build>

有人知道这里发生了什么吗？

更新

我尝试使用命令 mvn:tomcat7 deploy -X部署应用程序，输出为:

好的，tomcat7也有同样的问题。

[INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset

我无法使用它

mvn tomcat7:redeploy 

如 here所述。
我的WAR不是很大，只有4MB。
这是根本问题和解决方案
重要的是，您的 tomcat-users.xml必须具有正确的角色设置。我只有角色 manager设置。添加 manager-script似乎很重要，并且完全解决了我的问题。

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