Cannot invoke Tomcat manager: Software caused connection abort

Question

I have seen multiple locations where people besides myself have tried all solutions presented in this link, and after going through every page of results on Google, I have failed to find a result. I am trying to deploy a maven project to Tomcat, but I get the following printout:

[INFO] ------------------------------------------------------------------------

Both

mvn tomcat7:deploy

and

mvn tomcat7:redeploy

result in the same error.

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-users.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 (in both maven home and .m2 folder)

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

I am aware that my Tomcat version is 8, however, according to Borgy Manotoy, the Tomcat7 plugin will work for Tomcat 8.

The same problem, solved by right credentials in Maven settings.xml. Yes, this error messages are misleading:

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

We use profiles in pom.xml, so:

<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>

and set maven "Tomcat plugin":

<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>

and finally settings.xml in Maven/conf:

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

Deploy:

   mvn tomcat7:deploy -Pstage_server

I could upload the file from Postman so I knew the userid and password was right and the Tomcat server was setup correctly. I had the user and password in my settings.xml in the root of my project, but, it wasn't reading them and no error that it couldn't find my server. I moved the user and password directly into the POM.xml and it worked. I thought I had read I could put the settings.xml in the root of the project, but, I must be missing something. — J.

@J.Chaney I think you have to have the file settings.xml in Maven home directory in sub-directory "conf". If you have this file in Maven home/conf directory, will a deploy be successful? — Radek, Jan 15 '20 at 13:54

I had the same error...

Using Java 7 from Windows host, targeting Tomcat 7 running in a local VM (VirtualBox). Accessing the Manager's app. from my browser worked perfectly fine (/html or /text).

It seems that the manager-gui & manager-script roles cannot be granted to the same user. So, I ended up having that deployer user with the manager-script role with which I was able to execute the Maven commands properly after:

<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>
