maven项目依赖了几个额外的jar包一直都无法打进最终jar,不知道哪里出了问题.一直对这块不甚清楚,就大概梳理一下

默认打包方式:

　　maven项目下,默认编译目录为

src/main/java和src/test/java

　　和

src/main/resouces和src/test/resources

所以按照默认条件,其他目录的东西都不会被打进去,而且这些目录底下的一些非符合条件文件也不会被打包,java目录下只会打包.java文件,具体看target/classes目录下的文件即可

除非特别指定,否则,打包时将会把target/classes目录下的东西打包成jar

那么问题来了,怎么把想要加入打包的东西弄到目录target/classes下呢

这个是由resource决定的,当需要将一些特殊文件打包时,需要额外配置resource标签:

　　比如经常碰到的在src/main/java中写的xml需要打包到jar,需要配置:


            
                  
                      
                           
                            
        
         src/main/java
                             
                              
                              
         
          **/*.xml
                          
                                               
                              
                              
         
          **/*.yaml
                           
                           
                              
                                 
                            
        
         true

　　所以,如果要加入jar包同样需要加入resource


                     
      
       lib
                      
      
       BOOT-INF/lib/
                      
                          
       
        **/*.jar

把lib目录下的所有jar都加入到resource中,就能看到target/class目录下有这些jar包啦

不过jar包有了,还是会报错:

编译失败了,并且是因为缺少类引起的,而且是maven-compiler-plugin插件报错,检查发现,由于加入了新的资源,打包插件中也需要加入相应包路径:
