Issue in Changing the war file name generated by maven - maven

Question

I just followed this question and modified my pom to create different war file. Here is the original configuration
<build>
<finalName>${project.artifactId}</finalName>

Here is the Modified (want to create Cambellton.war)

When try to build, it gives error, but war file is created. I think it giving problem when trying to create the zip file. Here is the error message

Answer 1

In the Maven Assembly Plugin configuration, check the
<finalName>Cambellton{packname}</finalName>
the {packname} is not recognized as a property because missing the $ prefix. Assuming that you define packname as a property in your pom.
In your original configuration, it was
<finalName>LabSystem${packname}</finalName>
Also check consistency with your src/main/assembly/webapp.xml file, which could include any or the specified generated war file, as below example:
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
<id>zip</id>
<formats>
<format>zip</format>
</formats>
<fileSets>
<fileSet>
<directory>${project.build.directory}</directory>
<includes>
<include>*.war</include>
</includes>
<useDefaultExcludes>true</useDefaultExcludes>
</fileSet>
</fileSets>
</assembly>
Update
Base on your latest edits (adding the assembly configuration), I see several things which could be improved and the potential cause of error as well:
Your file defined in the source element is using the artifactId of the project, but you renamed it to be Cambellton, so you should also make it consistent with this change (${project.build.directory}/Cambellton.war instead of ${project.build.directory}/${project.artifactId}.war). This was causing the build error most probably
Instead of pointing to /${project.artifactId}/src I would replace it by ${project.basedir}/src (same for WebContent output directory)
