为maven-processor-plugin编写注释处理器 [英] Writing an annotation processor for maven-processor-plugin

问题描述

我有兴趣为maven-processor-plugin编写注释处理器。我对Maven来说比较新。

I am interested in writing an annotation processor for the maven-processor-plugin. I am relatively new to Maven.

项目路径中的处理器Java源代码应该去哪里（例如：src / main / java / ...）以便它适当编译，但不会作为我的工件JAR文件的一部分结束？

Where in the project path should the processor Java source code go (e.g.: src/main/java/...) so that it gets compiled appropriately, but does not end up as part of my artifact JAR file?

推荐答案

最简单的方法是保留注释处理器在一个单独的项目中包含为依赖项。

The easiest way is to keep your annotation processor in a separate project that you include as dependency.

如果这对您不起作用，请使用此配置

If that doesn't work for you, use this config

编译器插件：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
        <source>1.5</source>
        <target>1.5</target>
    </configuration>
    <inherited>true</inherited>
    <executions>
        <execution>
            <id>default-compile</id>
            <inherited>true</inherited>
            <configuration>
                <!-- limit first compilation run to processor -->
                <includes>path/to/processor</includes>
            </configuration>
        </execution>
        <execution>
            <id>after-processing</id>
            <phase>process-classes</phase>
            <goals>
                <goal>compile</goal>
            </goals>
            <inherited>false</inherited>
            <configuration>
                <excludes>path/to/processor</excludes>
            </configuration>
        </execution>
    </executions>
</plugin>

处理器插件：

<plugin>
    <groupId>org.bsc.maven</groupId>
    <artifactId>maven-processor-plugin</artifactId>
    <executions>
        <execution>
            <id>process</id>
            <goals>
                <goal>process</goal>
            </goals>
            <phase>compile</phase>
            <configuration>
                <processors>
                    <processor>com.yourcompany.YourProcessor</processor>
                </processors>
            </configuration>
        </execution>
    </executions>
</plugin>

（请注意，这必须在两次编译运行之间执行，因此必须放置此项上面的maven-compiler-plugin配置之后的pom.xml 中的代码）

(Note that this must be executed between the two compile runs, so it is essential that you place this code in the pom.xml after the above maven-compiler-plugin configuration)

Jar插件：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.3.1</version>
    <configuration>
        <excludes>path/to/processor</excludes>
    </configuration>
    <inherited>true</inherited>
</plugin>
