module-info.class問(wèn)題

1.module-info.class是個(gè)什么？干什么？

2.看名字module-info，即模塊信息，自然想到是管理模塊信息的。jdk9特性里的，在解壓軟件中直接干掉唄，試試沒(méi)報(bào)錯(cuò)ok就行

3.pom文件導(dǎo)入 asm等配置后啟動(dòng)報(bào)錯(cuò)

?? ??? ?<dependency>
?? ??? ??? ?<groupId>asm</groupId>
?? ??? ??? ?<artifactId>asm</artifactId>
?? ??? ??? ?<version>3.3.1</version>
?? ??? ?</dependency>

嚴(yán)重:

org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 19

log4j中也有，也干掉，這個(gè)層次jar位置再往下找META-INF/versions/9/module-info.class，編譯器都告訴你位置了，別傻傻的和前面那個(gè)一樣

META-INF/versions/9/module-info.class  解壓工具刪除掉（關(guān)掉IDE工具，刪完再運(yùn)行）

找到Maven下的jar包

查看jar包所在路徑

找到并刪除它

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
