龙目岛和Maven

标签： java maven intellij-idea lombok

我试图在IntelliJ上使用Lombok和Maven以及VRaptor，但它不起作用。

我已经在stackoverflow中读了一些信息，但没有解决我的问题，我已经在Intellij中启用了注释处理器，但仍然没有。

我也尝试从命令行编译它（Windows）并且没有工作。

我还尝试创建另一个没有maven的项目并添加库，创建一些用于测试的类，它可以正常工作，编译和运行。

任何帮助？

该项目只有2个类，1个实体和1个控制器

这是我的pom.xml

答案 1 :(得分：6)

这应该按原样运行，与IntelliJ的想法无关。但我会：

  • 确保@Data注释是lombok one
  • 删除存储库定义（maven central很好）
  • 使用最近的lombok版本（1.16.0 撰写本文）
  • 重建（mvn clean package）

我认为maven在你的情况下找不到lombok jar，或者你可能有另一个@Data。

尝试此依赖

在 projectId 标签中，尝试将 projectlombok.org 替换为 org.projectlombok

答案 4 :(得分：-2)

您需要添加lombok插件：

  <build>
  <plugins>
    <plugin>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok-maven-plugin</artifactId>
      <version>1.16.8.0</version>
      <executions>
        <execution>
          <phase>generate-sources</phase>
          <goals>
            <goal>delombok</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>
