You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

Process finished with exit code 1

I have a init sql under db/migration with name: V1.0.0__init.sql (just one line in it: use mydb;)

my flyway configuration in yml (ignore other datasource):

spring:
  flyway:
    baseline-on-migrate: true
    locations: classpath:db/migration

I tried to debug it, found the FlywayAutoConfiguratioin.hasAtLeastOneLocation() always return false, it means not found the location (but the location looks like right in debugger), see the following screenshot:

appreciate any kind help :)

回答1:

Make sure that you have not accidentally created a folder with the name db.migration, as opposed to the folders db/migration.
Intellij will show both as db.migration in the project files view, when you have the option "Compact Middle Packages" enabled.
