导入 Maven 模块中的 Lombok

Question

我有以下 Maven 结构：

parent-module
|-model-module
|-model-contributor-module

在model-module我有用 注释的实体@lombok.Data。当我穿上mvn clean install一切都好model-module。第二个内部模块model-contributor-module包含model-module依赖项。当我尝试执行相同的构建时model-contributor-module，我收到错误cannot find symbol。

pom.xml为了model-module：

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <scope>provided</scope>
</dependency>

对于：pom.xml​model-contributor-module

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <scope>provided</scope>
</dependency>
.....
<pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok-maven-plugin</artifactId>
                <version>1.16.8.0</version>
            </plugin>
        </plugins>
    </pluginManagement>
....
    <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.5.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok-maven-plugin</artifactId>
            <version>1.16.8.0</version>
            <configuration>
                <encoding>UTF-8</encoding>
            </configuration>
            <executions>
                <execution>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>testDelombok</goal>
                        <goal>delombok</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

如何修复这些编译错误？

[ERROR] /Users/superuser/Documents/workspace/project/test/src/main/java/com/company/services/impl/MyServiceImpl.java:[291,65] cannot find symbol
[ERROR] symbol:   method getUserId()

Answer 1

将该 lombok 依赖项移至父 pom 的 dependencyManagement 元素中，以便子模块可以继承它。您在所有模块中都可以使用该插件，但看起来 lombok 依赖项仅在模型模块中可用。

<dependencyManagement>
  <dependencies>
   ...
   <dependency> 
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <scope>provided</scope>
   </dependency>
  </dependencies>
</dependencyManagement>
