飞行错误:无法在Mac Sierra 10.13上加载

Question

我使用brew安装了飞行，我正在尝试为postgres运行迁移，我遇到了这个错误：

Flyway 4.2.0 BoxFuse

错误：无法加载/usr/local/cellar/flyway/4.2.0/libexec/drivers/postgresql-9.4.1208.jre6.jre6.jar

我已经检查了此路径，并且目录和文件存在。

有什么建议吗？

Answer 1

这是一个已知的问题（1545）4.x，该版本5.x

解决

解决方案：安装版本5.x-我向自制酿造提交了拉动请求以更新公式

根本原因是 ClassCastException-与Java 9更改有关（问题3）。

使用-X标志运行以查看实际问题：
