Maven / Jetty / Cannot override read-only parameter: contextPath in goal
Case
My project is deployed via Maven on a Jetty 6 server. I have to upgrade the server to Jetty 7.
(BTW: notice that the plugin maven-jetty-plugin was renamed as jetty-maven-plugin)
I get this error:
[java] Error configuring: org.mortbay.jetty:jetty-maven-plugin. Reason: ERROR: Cannot override read-only parameter: contextPath in goal: jetty:run-exploded[/java]
Quick fix
Insert a tag <webAppConfig> between <configuration> and <contextPath>. In other terms, replace this block:
[xml]<configuration>
<contextPath>/I/love/USA</contextPath>
</configuration>[/xml]
with that one:
[xml]<configuration>
<webAppConfig>
<contextPath>/I/love/USA</contextPath>
</webAppConfig>
</configuration>[/xml]
