求救！db.driverLocation路径问题！

Question

我已经从源码的tools里面将bin.jar拷贝了出来，并且将driverlocation指向了相应位置，却仍然无法generate

报错：

objc[4579]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

没事了，我的等号不小心打成日文格式的了。

如果有同学在这里出现问题的话，用log打印出来日志(打log方法：https://blog.csdn.net/sunny243788557/article/details/45166397)

，然后如果错误中有，请返回datasource,把数据库的ip地址db.url改为 本地（127.0.0.1 或者localhost）。

你好同学，改成绝对路径再试试，类似于下面这种形式

db.driverLocation=E:/imooc/mysql-connector-java-5.1.6-bin.jar

• 提问者 睡鼠Zzz #1

  问题是mac的绝对路径的起始盘找不到。。。我用Macintosh HD作为路径开头也不起作用。。。折腾了很久一直弄不好我很难过。。。

• 提问者 睡鼠Zzz #2

  会不会是这个问题啊，不过我还是觉得应该是路径没搞对。。。

  因为我的jdk是1.8的，所以配置pom.xml的时候，warning里面提到的@line 264已经更改成1.8
