自定义过滤器 Custom resources filters

With version 2.5 you are now able to build your own customresources filter(s).

Your custom resources filter classes must implements org.apache.maven.shared.filtering.MavenResourcesFiltering.

CustomResources Filter Implementation

Your custom resources filter classes must be marked as aPlexus Component. Below a sample with a roleHint itFilter.

1.  /**
2.   * @plexus.component role="org.apache.maven.shared.filtering.MavenResourcesFiltering" 
3.   *                   role-hint="itFilter"
4.   */
5.  public class ItFilter
6.      implements MavenResourcesFiltering

Then you must activate in your build the mojo which willscan javadoc annotations to transform thoses to plexus component metadata.

1.    <plugin>
2.      <groupId>org.codehaus.plexus</groupId>
3.      <artifactId>plexus-maven-plugin</artifactId>
4.      <version>1.3.4</version>
5.      <executions>
6.        <execution>
7.          <goals>
8.            <goal>descriptor</goal>
9.          </goals>
10.      </execution>
11.    </executions>
12.  </plugin>

Dependencydeclaration

Your classes must be available in the maven-resources-pluginclasspath, this can be done with adding your artifact to the plugindependencies.

1.  <project>
2.    ...
3.    <build>
4.      <plugins>
5.        <plugin>
6.          <groupId>org.apache.maven.plugins</groupId>
7.          <artifactId>maven-resources-plugin</artifactId>
8.          <version>3.1.0</version>
9.          <configuration>
10.          ...
11.        </configuration>
12.        <dependencies>
13.          <dependency>
14.            <groupId>custom resources filters artifact groupId</groupId>
15.            <artifactId>custom resources filters artifact artifactId</artifactId>
16.            <version>custom resources filters artifact version</version>
17.          </dependency>
18.        </dependencies>
19.      </plugin>
20.    </plugins>
21.    ...
22.  </build>
23.  ...
24.</project>

Useof your Custom Resource Filter with the maven-resources-plugin

You must now declare you custom filter in the plugin.mavenFilteringHint must respect same syntax as your Plexus Component roleHint.

1.    <plugin>
2.      <groupId>org.apache.maven.plugins</groupId>
3.      <artifactId>maven-resources-plugin</artifactId>
4.      <version>3.1.0</version>
5.      <configuration>
6.        ...
7.        <mavenFilteringHints>
8.          <mavenFilteringHint>itFilter</mavenFilteringHint>
9.        </mavenFilteringHints>
10.     </configuration>
11.     ...
12.   </configuration>
13. </plugin>
