Maven 无法调用Tomcat管理器：软件导致的连接中止

我曾在多个地方看到，除了我自己，其他人都尝试过中介绍的所有解决方案，在浏览了谷歌上的每一页结果后，我都没有找到结果。我正在尝试将maven项目部署到Tomcat，但得到以下打印输出：

两者

及

导致相同的错误

pom.xml

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <server>tomcat7</server>
        <path>/Project_2</path>
        <port>8085</port>
        <url>http://localhost:8085/manager/text</url>
        <update>true</update>
        <username>manager</username>
        <password>xxxx</password>
    </configuration>
</plugin>

org.apache.tomcat.maven
，Tomcat7插件将适用于Tomcat8。
我也有同样的错误

从Windows主机使用Java 7，目标是在本地VM（VirtualBox）中运行的Tomcat 7。访问经理的应用程序。从我的浏览器中可以很好地工作（
/html
或
/text
）

似乎不能将
manager gui
和
manager脚本
角色授予同一用户。因此，我最终让
deployer
用户担任
manager脚本
角色，在以下情况下，我能够正确执行Maven命令：

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

同样的问题，通过Maven settings.xml中正确的凭据解决了。是，此错误消息具有误导性：

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.2:deploy (default-cli) on project projectXXX: Cannot invoke Tomcat manager
...
Caused by: org.apache.maven.plugin.MojoExecutionException: Cannot invoke Tomcat manager
...
Caused by: java.net.SocketException: Connection reset by peer: socket write error

我们在pom.xml中使用概要文件，因此：

<profile>
   <id>stage_server</id>
   <activation>
      <activeByDefault>true</activeByDefault>
   </activation>
   <properties>
      <tomcat-server>stage-server</tomcat-server>
      <tomcat-url>http://stage.server.com/manager/text</tomcat-url>
   </properties>
</profile>

我可以从邮递员那里上传文件，这样我就知道用户ID和密码是正确的，Tomcat服务器的设置是正确的。我在我的项目根目录下的my settings.xml中有用户和密码，但是，它没有读取它们，并且没有错误，它找不到我的服务器。我将用户和密码直接移动到POM.xml中，它成功了。我想我已经读过了，我可以把settings.xml放在项目的根目录中，但是，我肯定遗漏了什么。@J.Chaney我想你必须把settings.xml文件放在Maven home目录的子目录“conf”中。如果您在Maven home/conf目录中有这个文件，部署会成功吗？
