Unable to install maven plugin

[thakurshishir]

Hi,
I have added the following plugin into pom.xml:

<plugin>
  <groupId>org.walkmod.maven.plugins</groupId>
   <artifactId>walkmod-maven-plugin</artifactId>
   <version>1.0.3</version>
   <executions>
      <execution>
         <phase>generate-sources</phase>
         <goals>
            <goal>apply</goal>
         </goals>
      </execution>
   </executions>
</plugin>

When I run this with maven plugin it gives the following error:

FATAL [main] - The markup declarations contained or pointed to by the document type declaration must be well-formed. at (-//WALKMOD//DTD:1:3)

Can you help resolving this issue?

Please, could you use the markdown language of GitHub?

Otherwise it becomes really hard. I would need the contents of your pom.xml file. Have you created any walkmod.xml file manually?

[rpau]

@thakurshishir I have updated your comment with markdown. Now it seems more clear. It seems that you have created a walkmod.xml file. Could you share the contents please?

[thakurshishir]

At first I tried without creating walkmod.xml, but the same error was thrown during maven build.

So, I created walkmod.xml into the project repository with different formats:

<!DOCTYPE walkmod PUBLIC "-//WALKMOD//DTD" "http://www.walkmod.com/dtd/walkmod-1.0.dtd">
<walkmod>
<plugins>
	<plugin groupId="org.walkmod" artifactId="walkmod-imports-cleaner-plugin" version="2.0"/>
</plugins>
<chain name="example-chain">
<transformation type="walkmod:commons:import-cleaner"/>
</chain>
</walkmod>

<!DOCTYPE walkmod PUBLIC "-//WALKMOD//DTD"  "http://www.walkmod.com/dtd/walkmod-1.0.dtd" >
<walkmod>
	<plugins>
		<plugin groupId="org.walkmod" artifactId="walkmod-imports-cleaner-plugin"
			version="2.0" />
	</plugins>
	<chain name="example-chain">
		<reader path="src/" />
		<transformation type="walkmod:commons:import-cleaner" />
	</chain>
</walkmod>

<!DOCTYPE walkmod PUBLIC "-//WALKMOD//DTD"  "http://www.walkmod.com/dtd/walkmod-1.0.dtd" > 
 <walkmod> 
	<plugins> 
 		<plugin groupId="org.walkmod" artifactId="walkmod-imports-cleaner-plugin" 
 			version="2.0" /> 
 		<plugin groupId="org.walkmod" artifactId="walkmod-license-applier-plugin" 
 			version="2.0" /> 
 		<plugin groupId="org.walkmod" artifactId="walkmod-setter-getter-plugin" 
 			version="2.0" /> 
 	</plugins>
 	<chain name="common"> 
 		<transformation type="walkmod:commons:import-cleaner" /> 
 		<transformation type="walkmod:commons:license-generator"> 
 			<param name="licenseFile">src/main/license-header.txt</param> 
 		</transformation> 
 	</chain> 
</walkmod>

Remove the walkmod.xml file and use this command:

walkmod apply imports-cleaner

Alternatively, you can create a walkmod.xml file with these contents:

<!DOCTYPE walkmod PUBLIC "-//WALKMOD//DTD" "http://www.walkmod.com/dtd/walkmod-1.1.dtd">
<walkmod>
<transformation type="imports-cleaner"/>
</walkmod>

If it does not work, probably is because you are using a proxy server.

Thanks for the update on the issue.
We were using remote desktop where this is not working. So, now I have switched to my local machine where walkmod apply imports-cleaner is working.
But I am encountering another issue for this.
For some files code transformation is working where the unused imports are removed. But for some files it is giving below error:

Ok, thanks for the stacktrace.
