为 maven-processor-plugin 编写注释处理器

发布于 2024-10-21 18:17:36 字数 149 浏览 1 评论 0原文

我有兴趣为 maven-processor-plugin 编写一个注释处理器。我对 Maven 比较陌生。

处理器 Java 源代码应该位于项目路径中的哪个位置（例如：src/main/java/...），以便正确编译它，但最终不会成为我的工件 JAR 文件的一部分？

最简单的方法是将注释处理器保留在作为依赖项包含的单独项目中。

如果这对您不起作用，请使用此配置

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，因此至关重要将此代码放置在 pom.xml 之后上述 maven-compiler-plugin 配置）

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>

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

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

Compiler Plugin:

<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>

Processor Plugin:

<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>

(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 Plugin:

<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>
