Filter maven resources with filter-file from external dependency

问题

Given a property file in maven project A

I want to use them in project B for resource filtering.

So in Project B I use

<build>
        <filters>
            <filter>${project.build.directory}/myFile.properties</filter>
        </filters>
 </build>

To filter my resources based on values in myFile.properties This file is stored in project A. So I include it with

    <build>
  <plugins>
    <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <id>unpack</id>
                    <phase>process-resources</phase>
                    <goals>
                        <goal>unpack</goal>
                    </goals>
                    <configuration>
                        <artifactItems>
                            <artifactItem>
                                <groupId>groupa</groupId>
                                <artifactId>a</artifactId>
                                <version>${project.version}</version>
                                <type>test-jar</type>
                                <outputDirectory>${project.build.directory}</outputDirectory>
                            </artifactItem>
                        </artifactItems>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Problem is that the resource filtering happens before the dependency is copied. So filtering does work when copying myFile.properties manually to ${project.build.directory} but it does not work with a mvn clean ...

How can I copy the filterFile before the actual filtering happens?

回答1:

Maven plugins are executed in the order they appear in the pom. AFAIK the plugins configured in the parent (and the super pom) are executed before the plugins of the pom.

My suggestion is declaring the resources plugin explicitely after the dependency plugin:

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-dependency-plugin</artifactId>
      <!-- ... -->
    </plugin>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-resources-plugin</artifactId>
      <!-- ... -->
    </plugin>
  </plugins>
</build>
