When running "mvn test" on command prompt, error was encountered

Question

When running "mvn test" on command prompt, error was encountered. I need to run "mvn test" to test report JUnit plugin with Maven and Java.

Command prompt:

[ERROR] Error executing Maven. [ERROR] 1 problem was encountered while building the effective settings [FATAL] Non-parseable settings C:\Program Files\apache-maven-3.6.0\bin..\conf\settings.xml: end tag name must match start tag name from line 102 \n -->\n... @254:12> @ C:\Program Files\apache-maven-3.6.0\bin..\conf\settings.xml, line 254, column 12

Answer 1

Non-parseable settings

C:\Program Files\apache-maven-3.6.0\bin..\conf\settings.xml: end tag name must match start tag name from line 102

Your settings.xml file has some syntax errors, try the below content:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <!-- localRepository | The path to the local repository maven will use to 
        store artifacts. | | Default: ${user.home}/.m2/repository -->
    <localRepository>C:\Users\hiddenuser\.m2\repository</localRepository>

    <!-- interactiveMode | This will determine whether maven prompts you when 
        it needs input. If set to false, | maven will use a sensible default value, 
        perhaps based on some other setting, for | the parameter in question. | | 
        Default: true <interactiveMode>true</interactiveMode> -->

    <!-- offline | Determines whether maven should attempt to connect to the

    <!-- pluginGroups | This is a list of additional group identifiers that

    <pluginGroups>
        <!-- pluginGroup | Specifies a further group identifier to use for plugin 
            lookup. <pluginGroup>com.your.plugins</pluginGroup> -->
    </pluginGroups>

    <proxies>
        <proxy>
            <id>optional</id>
            <active>true</active>
            <protocol>http</protocol>
            <!-- <username></username> <password></password> -->
            <host>hidden only</host>
            <port>hidden only</port>
            <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
        </proxy>
    </proxies>

    <!-- servers | This is a list of authentication profiles, keyed by the server-id 
        used within the system. | Authentication profiles can be used whenever maven 
        must make a connection to a remote server. | -->
    <servers>
    </servers>
</settings>

You haven't specified the ending matching /servers and /settings in the settings.xml file, that's why you are getting 'Non-parseable settings' error.

Answer 2

At line no : 92 you just comment the opening of <servers> and at line no 102 it's closing <servers>, the error says itself that, you pass the unnecessary comment on the tag please remove the comment sign..

end tag name must match start tag name from line 102

So update the file and execute it again and let us know that this solution is helped you or not
