[nireno]

Which version and edition of Flyway are you using?

5.0.7

Which client are you using? (Command-line, Java API, Maven plugin, Gradle plugin)

Command-line

Which database are you using (type & version)?

Postgres 9.5.11

Which operating system are you using?

Linux Mint 18.2 Sonya

What did you do?

On a fresh database I attempted to run flyway on a folder containing a single migration:
flyway -url=jdbc:postgresql://localhost:5432/mytest -user=myuser -password=mypass -locations=filesystem:/home/myuser/sql/migrations migrate

/home/myuser/sql/migrations/V1__initial_create:

CREATE TABLE test_table (
	id          SERIAL PRIMARY KEY,
	some_column TEXT
);

COPY test_table (id, some_column) FROM stdin;
1	
\.

What did you expect to see?

A "migration success" message.

What did you see instead?

ERROR: Migration of schema "public" to version 1 - initial create failed! Changes successfully rolled back.
ERROR: 
Migration V1__initial_create.sql failed
-----------------------------------------

Other notes

Note that there is a trailing tab after the 1 in the COPY'd row. The migration seems to fail whenever the last row ends with a tab. The migration process succeeds if I add another that row does not end with a tab, like:

COPY test_table (id, some_column) FROM stdin;
1	
2	something
