问题引入
在项目中，编译代码过程中出现了如下问题：

其中核心的错误信息如下：
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project mall-tms-waybill-dao: Fatal error compiling: java.lang.ExceptionInInitializerError: com.sun.tools.javac.code.TypeTags -> [Help 1]
从直观的错误信息判断，好像是与maven-compiler-plugin有关，从root cause中可知，其底层原因是：
Caused by: java.lang.ClassNotFoundException: com.sun.tools.javac.code.TypeTags
这个类找不到，这个是什么类？从类名来看是JDK中sun的私有类，可以判断其与JDK有关系，或类在不同JDK下的兼容性有关
问题分析
网络上的文章大部分是提到Lombok的版本，检查了一下：
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.16</version>
</dependency>
这个版本是最新的。
检查了一下maven的基本信息：
mvn -version
输出信息如下：
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /usr/local/Cellar/[email protected]/3.3.9_1/libexec
Java version: 15.0.1, vendor: N/A
Java home: /usr/local/Cellar/openjdk/15.0.1/libexec/openjdk.jdk/Contents/Home
Default locale: zh_CN_#Hans, platform encoding: UTF-8
OS name: "mac os x", version: "10.15.5", arch: "x86_64", family: "mac"
之前使用了brew安装maven:
brew install [email protected]
默认情况下直接安装了maven
尝试解决
尝试1: 重新安装maven至最新版本
brew install maven
问题依旧。
尝试2: 重新安装maven，指定–ignore-dependencies，不安装依赖
brew install --ignore-dependencies maven
安装输出信息如下：
Warning: `--ignore-dependencies` is an unsupported Homebrew developer flag!
Adjust your PATH to put any preferred versions of applications earlier in the
PATH rather than using this unsupported flag!
查看brew install的帮助文档，信息如下：
brew install -h
输出信息如下：
--ignore-dependencies An unsupported Homebrew development flag to
skip installing any dependencies of any
kind. If the dependencies are not already
present, the formula will have issues. If
you're not developing Homebrew, consider
adjusting your PATH rather than using this
flag.
结论： 依然无法解决问题。
正确姿势
那就尝试手动安装maven吧。
- 下载maven(maven.apache.org)
- 解压安装
> tar -zxvf apache-maven-3.6.3.tar.gz
- 设置环境变量
写入～/.zshrc
export MAVEN_HOME=~/apache-maven-3.6.3
export PATH= P A T H : PATH: PATH:MAVEN_HOME/bin
生效设置:
source ~/.zshrc
其他类似的文件： ~/.zshenv
检查maven的版本信息:
mvn -version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /Applications/apache-maven-3.6.3
Java version: 1.8.0_282, vendor: Oracle Corporation, runtime: /usr/local/Cellar/[email protected]/1.8.0+282/libexec/openjdk.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.15.5", arch: "x86_64", family: "mac"
重新编译执行即可正确通过
总结
这里的问题是maven使用的JDK版本与系统默认代码编译的JDK版本不一致导致的。
