| Re: [jetty-users] jetty-maven-plugin, war overlay and hot redeploy |
Ivan,
Re my previous posting, I can confirm that what I described works in
jetty: if the dependency war changes in local maven repo jetty will
redeploy, re-unpack it and use the changed static resources, classes
etc.
Having re-re-read your stackoverflow post, I think I see the problem:
the plugin is using the classes and resources from your dependency
war, NOT from the <scanTarget> that you have added. The <scanTarget>
simply tells jetty to watch that location and redeploy if something in
it changes.
So you need to tell jetty to use the classes and resources from your
dependency war's project, NOT the war artifact.
So do something like:
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.2.3.v20140905</version>
<configuration>
<webApp>
<!-- tell jetty to use the classes from the dependency
webapp project directly -->
<extraClassPath>${basedir}/../SharedWeb/target/classes</extraClassPath>
<!-- tell jetty to use both this project's static
resources, and those of the dependency webapp project -->
<resourceBases>
<directory>${basedir}/src/main/webapp</directory>
<directory>${basedir}/../SharedWeb/src/main/webapp</directory>
</resourceBases>
</webApp>
<scanIntervalSeconds>3</scanIntervalSeconds>
<!-- tell jetty to watch the dependency webapp project classes
dir for changes -->
<scanTargets>
<scanTarget>${basedir}/../SharedWeb/target/classes/</scanTarget>
</scanTargets>
</configuration>
</plugin>
