R – Ant replace in maven2

antbuild-processconfigurationmaven-2

I'm looking for some way to replace patterns in files with values, during build time.

E.g. a configuration file may look the same except that different machines requires different hostnames in some setting. In that case i want to have a template file, where hostname is replaced with @@hostname@@
Then when building, I want to create separate versions of the file with the patter replaced with the correct value for each environment.

In ant you could use "replace", is there something similar in maven2? I know that I can run ant form maven, but if theres a maven plugin doing it, I'd prefer that one.

I found http://code.google.com/p/maven-replacer-plugin/
but it's very new…

Suggestions?

Thanks!

The resource plugin is what does filtering in Maven. IIRC it supports the ant syntax as well as the ${foo} maven syntax.

Java – Difference of Maven JAXB plugins

Let's summarize. We have/had:

Based on the comments of this thread, I've always used the maven-jaxb2-plugin (i.e. plugin #1):

Concerning the org.jvnet.jaxb2.maven2:maven-jaxb2-plugin versus com.sun.tools.xjc.maven2:maven-jaxb-plugin, from my point of view it's definitely the first one (http://maven-jaxb2-plugin.java.net/).

This plugin has much more features than com.sun.tools.xjc.maven2:maven-jaxb-plugin, the development is active. Finally, I'm one of the authors :) and I'd say we keep in touch with JAXB developers and users and react to the latests features/requests.

And indeed, the plugin #2 is dead. And because I've always been happy with #1, I've never used plugin #3 so can't really say anything about it. Just in case, here is a working configuration for plugin #1:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <inherited>true</inherited>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.5</source>
          <target>1.5</target>
        </configuration>
      </plugin>
      <plugin>
        <groupId>org.jvnet.jaxb2.maven2</groupId>
        <artifactId>maven-jaxb2-plugin</artifactId>
        <executions>
          <execution>
            <goals>
              <goal>generate</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>
