LombokはMavenでコンパイルしていません

Lavenkを使用するプロジェクトをmavenでコンパイルしようとしていますが、次の問題が発生しています。

最初のエラータイプは、このクラスのフィールドです。

package com.mangusbrother.akka.calculator.lib.operation.multiply;


import com.mangusbrother.akka.calculator.lib.operation.MathematicalResult;
import lombok.Data;

/**
 * Created by Mangusbrother on 14/02/2016.
 */
@Data
public class MultiplyResult implements MathematicalResult {
    private static final long serialVersionUID = 738641818941986L;
    private final int firstNumber;
    private final int secondNumber;
    private final int result;
}

2番目のエラーは、クラスがロンボククラスからゲッターにアクセスしようとした場合です。

私のmaven pom.xmlには次のものが含まれています。

理由はわかりませんが、maven-compiler-pluginが原因でコンパイラエラーが発生しました。プラグインのバージョンを3.5に変更して、機能するかどうかを確認してください。

私はこれに非常に苦労し、Lombok 1.16 +およびJava 8はMavenのコンパイラプラグインの以前のバージョンの問題であると結論付けました。 IDEA 2017.1はエラーなしでコードをビルドしていましたが、Mavenは逆コンパイルされたjarファイルに確実に存在するパブリックメソッドで「シンボルが見つかりません」エラーをスローしていました。

プロジェクトとそのライブラリ全体でmaven-compiler-plugin 3.6.1にアップグレードすることで、デロンボクのパスをたどることなく解決できるようになりました。

また、Javaのバージョンがパスにあることを確認する必要があります。私の問題はJava 1.8＆3.5 versionでした。 1.7と3.5に切り替えます。まだ1.7になっています。

最初に、lombokソース（lombokで注釈されたJava）をsrc/main/lombokに配置し、プロジェクトに lombok-maven-plugin を次のように追加する必要があります。

<build>
  <plugins>
    <plugin>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok-maven-plugin</artifactId>
      <version>1.16.6.1</version>
      <executions>
        <execution>
          <phase>generate-sources</phase>
          <goals>
            <goal>delombok</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

Lombok-maven-pluginを使用したくない場合は、次を追加する必要があります。

<dependencies>
  <dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.16.6</version>
    <scope>provided</scope>
  </dependency>
</dependencies>

デフォルトのsrc/main/Javaの代わりに/src/main/lombokにロンボクしたソースを配置することが本当に好きな場合 この方法で行かなければなりません これは推奨されません：

<build>
  <sourceDirectory>target/generated-sources/delombok</sourceDirectory>
  <testSourceDirectory>target/generated-test-sources/delombok</testSourceDirectory>
  <plugin>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok-maven-plugin</artifactId>
    <version>1.16.6.1</version>
    <executions>
      <execution>
        <id>delombok</id>
        <phase>generate-sources</phase>
        <goals>
          <goal>delombok</goal>
        </goals>
        <configuration>
          <addOutputDirectory>false</addOutputDirectory>
          <sourceDirectory>src/main/Java</sourceDirectory>
        </configuration>
      </execution>
      <execution>
        <id>test-delombok</id>
        <phase>generate-test-sources</phase>
        <goals>
          <goal>testDelombok</goal>
        </goals>
        <configuration>
          <addOutputDirectory>false</addOutputDirectory>
          <sourceDirectory>src/test/Java</sourceDirectory>
        </configuration>
      </execution>
    </executions>
  </plugin>
</build>
