在命令行上运行Flyway并没有找到SpringJdbcMigrations

Question

我正在尝试设置一个流程，我们从命令行运行Flyway来运行迁移（由于我的DBA对我的一些限制）

我在大多数情况下都很好地工作，找到并运行SQL和普通的JdbcMigrations，但它不会识别我的SpringJdbcMigrations，声称它没有Spring Jdbc可用。

下面，从flyway中找到我的文件结构，属性和调试输出：

文件结构

flyway.properties

#
# License removed for brevity

# Jdbc url to use to connect to the database
flyway.url=jdbc:mysql://localhost:3306/my_project

# User to use to connect to the database (default: <<null>>)
flyway.user=root

# Password to use to connect to the database (default: <<null>>)
flyway.password=XXXXXXX

# Comma-separated list of locations to scan recursively for migrations. (default: filesystem:<<INSTALL-DIR>>/sql)
# The location type is determined by its prefix.
# Unprefixed locations or locations starting with classpath: point to a package on the classpath and may contain both sql and java-based migrations.
# Locations starting with filesystem: point to a directory on the filesystem and may only contain sql migrations.
flyway.locations=classpath:com.mycompany.myproject.db.migration,filesystem:sql

# NOTE: All other properties are left as default

调试输出：

如果我能提供的任何其他信息可能会有所帮助，请告知我们。

编辑： 我还尝试修改shell shell脚本，直接将spring-jdbc jar添加到其类路径中。使用该修改运行没有引起明显的变化。

运行该更改（在更新的数据库之上，没有调试标志）产生了这个结果：

Answer 1

所以，我找到了一种让它工作的方法，但它需要修改“flyway”shell脚本中的类路径，这看起来很可疑，并且还需要包含FIVE依赖项，否则我要么得到描述的行为在问题中，或ClassNotFoundException。

具体来说，我需要将以下库添加到jars目录：

• commons-logging
• 弹簧豆
• spring-core
• spring-jdbc
• 弹簧-TX

将https://github.com/flyway/flyway/blob/flyway-3.0/flyway-commandline/src/main/assembly/flyway#L52更改为

"$JAVA_CMD" -cp ./bin/flyway-commandline-${project.version}.jar:./bin/flyway-core-${project.version}.jar:./jars/* org.flywaydb.commandline.Main $@ -consoleWidth=$CONSOLE_WIDTH

或4.0，https://github.com/flyway/flyway/blob/master/flyway-commandline/src/main/assembly/flyway#L57至

CP="./bin/flyway-commandline-${project.version}.jar:./bin/flyway-core-${project.version}.jar:./jars/*"

有更聪明的方法吗？这是在任何地方记录的吗？
