Replace default clean

Clean goal also uses go clean command so that it needs loading Golang SDK (if it is not provided). if you don't want such effect for cleaning then you can make some workaround

1. Disable the default clean processing by the wrapper, just add execution section among executions of the wrapper

<execution>
  <id>default-clean</id>
  <phase>none</phase>
</execution>

It will turn off default cleaning mechanism of the wrapper and Golang SDK will not be downloaded.

2. You still can use standard maven cleaning plugin and remove files and folders manually, just add the plugin with list of files and folders to be removed into build

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-clean-plugin</artifactId>
  <version>3.0.0</version>
  <configuration>
     <followSymLinks>false</followSymLinks>
     <excludeDefaultDirectories>true</excludeDefaultDirectories>
     <filesets>
       <fileset>
         <directory>${basedir}/bin</directory>
       </fileset>
     </filesets>
  </configuration>
</plugin>
