使用 maven-compiler-plugin 处理 Maven 注释 [英] Maven annotation processing with maven-compiler-plugin

问题描述

我尝试编译包含生成源代码的注释的代码.我使用 maven-compiler-plugin 和 build-helper-maven-plugin.我的 POM 看起来像这样:

I try to compile my code that contains annotations that generate source code. I use the maven-compiler-plugin and build-helper-maven-plugin. My POM is looking like that:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
                <generatedSourcesDirectory>${project.build.directory}/generated-sources/apt</generatedSourcesDirectory>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>build-helper-maven-plugin</artifactId>
            <version>1.5</version>
            <executions>
                <execution>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>add-source</goal>
                    </goals>
                    <configuration>
                        <sources>
                            <source>${project.build.directory}/generated-sources/apt</source>
                        </sources>
                    </configuration>
                </execution>
            </executions>
        </plugin>

当我运行mvn compile时，将${project.build.directory}/generated-sources/apt添加为源目录，并生成生成的源在正确的目录中.但是由于缺少对生成的类的引用，我得到了编译器错误.就好像生成的源目录没有包含在编译过程中.

When I run mvn compile, ${project.build.directory}/generated-sources/apt is added as a source directory, and the generated sources are generated in the correct directory. But I get compiler errors because of missing references to the generated classes. It's like the generated source directory is not included in the compilation process.

我也尝试了 apt-maven-plugin 它不会产生任何东西.和 maven-annotation-plugin 但它的行为如上所述.

I also try apt-maven-plugin which does not generate anything. And maven-annotation-plugin but it behaves as describe above.

推荐答案

能不能试试最新版的 maven 编译器插件(2.3.2)?

Can you try with the latest version of maven compiler plugin (2.3.2)?

此外 build-helper-maven-plugin 不是必需的，因为看起来您正在使用 maven-compiler-plugin 本身从注释生成源代码.

Also build-helper-maven-plugin is not required since it looks like you are using the maven-compiler-plugin itself to generate the sources from the annotation.
