CAUSE

Maven does not support spaces and certain special characters. When the maven password contains such un-supported characters, the maven deploy fails with 401 Unauthorized error.

SOLUTION

This issue can be solved in any of the following ways.

1. Encrypting the password: 

The password containing special characters can be encrypted and used in settings.xml as mentioned in this knowledge article: How to define encrypted passwords in the maven plugin

2. Using CDATA section: 

The password containing special characters can be saved in CDATA section.
  • Password can be saved in .m2/settings.xml file like below, where the password is P@$$w0^d(
<settings>
...
  <servers>
...
    <server>
      <id>anypointPlatform</id>
      <username>myUser</username>
      <password><![CDATA[P@$$w0^d(]]></password>
    </server>
...
  </servers>
...
</settings>
 
  • Password can also be saved in pom.xml like below, where the password is P@$$w0^d(
<plugin>
    <groupId>org.mule.tools.maven</groupId>
    <artifactId>mule-maven-plugin</artifactId>
    <version>${mule-maven-plugin.version}</version>
    <configuration>
        <deploymentType>arm</deploymentType>
        <username>myUser</username>
        <password><![CDATA[P@$$w0^d(]]></password>
        <applicationName>appname</applicationName>
        <businessGroup>${deploy.businessGroup}</businessGroup>
        <environment>${deploy.environment}</environment>
        <target>${deploy.target}</target>
        <targetType>${deploy.targetType}</targetType>
        <redeploy>true</redeploy>
    </configuration>
    <executions>
        <execution>
            <id>deploy</id>
            <phase>deploy</phase>
            <goals>
                <goal>deploy</goal>
            </goals>
        </execution>
    </executions>
</plugin>
