记录一个Lombok，在jdk10下面无法启动的问题，lombok.javac.apt.LombokProcessor could not be initialized.

0x00 - 还是废话不多说了，标题佛性一点
lombok版本： 1.16.20
maven配置如下

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>
                <source>10</source>
                <target>10</target>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok-maven-plugin</artifactId>
            <version>1.16.20.0</version>
        </plugin>
    </plugins>
</build>

IDEA 项目配置JDK版本为JDK10。

排坑的时候发现如果不配置maven-compiler-plugin，项目是可以启动的。
如果配置了maven-compiler-plugin，启动项目的时候，会抛出一个警告

然后提示

Error:(27, 37) java: 找不到符号
  符号:   方法 builder()
  位置: 类 com.tooldin.cms.core.entity.TestEntity

对，没错，你发现的lombok，在编译器也不会抛红，就是运行不起来，什么找到不到符号，getXXX()，setXXX()找不到，都是类似的，抛出lombok.javac.apt.LombokProcessor could not be initialized. Lombok will not run during this compilation: java.lang.IllegalArgumentException

0x01 - 解决方案
方案一：
毕竟我算是在尝鲜，所以解决方案1就是，把JDK降回JDK1.8，据说JDK1.9，也会有问题。

方案二：
升级Lombok，stackoverflow大神说可以升级到1.16.21，但毕竟我此时此刻在http://mvnrepository.com/ 并没有，有需要的可以在https://www.projectlombok.org/download-edge下载，version: 1.16.21 (2018-05-04 11:49:59 UTC)。嗯，我发布这篇文章是2018-05-16 20:00:01，所以我先用方案一解决了。祝大家愉快~
