maven-replacer-plugin and multiple files

This seems to be a bug in the latest 1.5.2 Version.

As soon as I change the version on bugfix level down to 1.5.1, the Not Working Example works just as expected and all tokens are replaced by their values.

<plugin>
  <groupId>com.google.code.maven-replacer-plugin</groupId>
  <artifactId>replacer</artifactId>
  <version>1.5.1</version>
  <executions>
    <execution>
      <phase>prepare-package</phase>
      <goals>
        <goal>replace</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <includes>
      <include>${project.build.directory}/myApp/index.jsp</include>
    </includes>
    <replacements>
      <replacement>
        <token>%PROJECT_VERSION%</token>
        <value>${project.version}</value>
      </replacement>
    </replacements>
  </configuration>
</plugin>

I also removed the ignoreMissingFile as suggested by ben.

The includes tag works with version 1.5.2 as well, you just have to specify the basedir tag before includes, and put the filepath (excluding the filename) as the basedir value and just the filename as the include tag value. So in your case something like this should work:

<plugin>
      <groupId>com.google.code.maven-replacer-plugin</groupId>
      <artifactId>replacer</artifactId>
      <version>1.5.2</version>
      <executions>
        <execution>
          <phase>prepare-package</phase>
          <goals>
            <goal>replace</goal>
          </goals>
        </execution>
      </executions>
      <configuration>
        <basedir>${project.build.directory}/myApp</basedir>
        <includes>
          <include>index.jsp</include>
        </includes>
        <replacements>
          <replacement>
            <token>%PROJECT_VERSION%</token>
            <value>${project.version}</value>
          </replacement>
        </replacements>
      </configuration>
    </plugin>
