使用迁飞与SBT如何能flywayUrl可以通过系统属性（指定-D ），而不是通过build.sbt ？
我想通过运行命令行迁移，而不会在定义它们指定了所有参数（驱动程序，URL，用户名，密码） build.sbt 。
该插件文档页面似乎表明，这应该是可能的：
为了重写
系统属性>插件配置
我试着运行它是这样的：
sbt -Dflyway.url=jdbc:h2:file:target/foobar -Dflyway.user=SA flywayMigrate
但flyway.url财产似乎有利于中被忽略flywayUrl中定义的属性build.sbt 。
考虑到这些文件的项目：
build.sbt
libraryDependencies ++= Seq(
"com.h2database" % "h2" % "1.3.174"
)
seq(flywaySettings: _*)
flywayUrl := "something that should be overriden"
项目/ plugins.sbt
addSbtPlugin("com.googlecode.flyway" % "flyway-sbt" % "2.3")
resolvers += "Flyway" at "http://flywaydb.org/repo"
的src /主/资源/分贝/迁移/ V1__Create_person_table.sql
create table PERSON (
ID int not null,
NAME varchar(100) not null
);
运行此命令：
$ sbt -Dflyway.url=jdbc:h2:file:target/foobar -Dflyway.user=SA flywayMigrate
产生这个错误：
