Maven tomcat 部署失败（对等方重置连接）

Question

我能够使用 webapp 将我的 WAR 文件部署到 tomcat 管理器，但是当我尝试使用 maven 插件 (tomcat7:deploy) 执行此操作时，几秒钟后上传失败（~3 兆字节）并出现此错误：

[ERROR] Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.0:deploy (default-cli) on project {project_name}: Cannot invoke Tomcat manager: Connection reset by peer: socket write error -> [Help 1]

POM的相关位如下：

                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <configuration>
                    <url>http://localhost:8080/manager/text</url>
                    <server>TomcatServer</server>
                    <update>true</update>
                </configuration>

在 maven conf/settings.xml 中定义的 TomcatServer 为：

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

什么可能导致连接重置？我在 conf/server.xml 中增加了超时，但没有帮助。

Answer 1

maven 设置首选项指向了错误的位置（它们可以在 eclipse 中更改：window -> 首选项 -> maven -> 用户设置）。我的默认为 /.m2/settings.xml，它不存在。使用 redeploy 目标而不是 deploy 来澄清上传实际上立即失败也很有帮助。
