java.net.socketexception connection reset by peer socket write error 通过Jenkins在Tomcat7上部署war时（使用Maven）

Question

I am trying to deploy a maven based web project on tomcat7 through Jenkins. When i try to execute maven goal "mvn tomcat7:deploy" from my command prompt, it works all fine and deploy the application on running tomcat7 instance. Now i set up a Job on Jenkins for the same Projects and getting socket error. Below is my code and the stacktrace from Jenkins console.

Entry in POM.xml

<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>Tomcat7Server</server>
            <path>/ElecnorMPR</path>
        </configuration>
    </plugin>

Apache Maven Settings.xml

<server>
  <id>Tomcat7Server</id>
  <username>tomcat</username>
  <password>tomcat</password>
</server>

Already defined the users in tomcat-user.xml.

Answer 1

I also faced this error while deploying war in heroku. But after redeploying it successfully deployed

Answer 2

Depending on the maven repository that is being used it is possible that a version policy or an existing artifact is causing the repository to close the connection. This may happen with or without a proper error message.

My issue was caused by the former using Gradle and Nexus. It did only issue the proper error in a different project.
