maven - 无法调用 Tomcat 管理器 : Software caused connection abort

Question

我在多个位置看到了除我以外的人尝试过 this link 中提供的所有解决方案的地方，在浏览了 Google 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，但我得到以下打印输出:

两者

mvn tomcat7:deploy

和

mvn tomcat7:redeploy

导致同样的错误。

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>

tomcat-用户.xml

<role rolename="manager-script"/>
<role rolename="manager-gui"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<role rolename="admin-gui"/>
<user username="admin1" password="xxxx" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-gui" />
<user username="manager" password="xxxx" roles="manager-script,admin-script" />

settings.xml(在 maven home 和 .m2 文件夹中)

<server>
  <id>tomcat7</id>
  <username>manager</username>
  <password>xxxx</password>
</server>

我知道我的 Tomcat 版本是 8，但是，根据 Borgy Manotoy ，Tomcat7 插件将适用于 Tomcat 8。

同样的问题，通过 Maven settings.xml 中的正确凭证解决。是的，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 中使用配置文件，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>

并设置maven“Tomcat插件”:

<plugin>
   <groupId>org.apache.tomcat.maven</groupId>
   <artifactId>tomcat7-maven-plugin</artifactId>
   <version>2.2</version>
   <configuration>
      <url>${tomcat-url}</url>
      <server>${tomcat-server}</server>
      <update>true</update>
   </configuration>
</plugin>

最后是 Maven/conf 中的 settings.xml:

<server>
  <id>stage-server</id>
  <username>admin</username>
  <password>xxxxx</password>
</server>

部署:

   mvn tomcat7:deploy -Pstage_server
