module-info.class问题
module-info.class是个什么？干什么？
看名字module-info，即模块信息，自然想到是管理模块信息的。jdk9特性里的，在解压软件中直接干掉呗，试试没报错ok就行
pom文件导入 asm等配置后启动报错
<dependency> <groupId>asm</groupId> <artifactId>asm</artifactId> <version>3.3.1</version> </dependency>严重:
Unable to process Jar entry [module-info.class] from Jar [jar:file:/D:/soft/repository/org/ow2/asm/asm/7.1/asm-7.1.jar!/] for annotations
org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 19
log4j中也有，也干掉，这个层次jar位置再往下找META-INF/versions/9/module-info.class，编译器都告诉你位置了，别傻傻的和前面那个一样
Unable to process Jar entry [META-INF/versions/9/module-info.class] from Jar [jar:file:/D:/soft/repository/org/apache/logging/log4j/log4j-api/2.12.0/log4j-api-2.12.0.jar!/] for annotations
找到对应maven仓库的位置 /D:/soft/repository/org/apache/logging/log4j/log4j-api/2.12.0/log4j-api-2.12.0.jar!/下的
META-INF/versions/9/module-info.class 解压工具删除掉（关掉IDE工具，删完再运行）
Tomcat报错module-info.class

以第一个报错为例
processAnnotationsJar

找到Maven下的jar包
查看jar包所在路径
找到并删除它
