Error: Could not find or load main class net.twentyonesolutions.m2pg.PgMigrator

[bryancjacobs]

This project doesn't appear to work with postgres 10.

After rewriting the bash script to work on my mac, the generated DDL will not execute.

Did you download the lib files from the release page?

I am having the same error. and I'm using Postgres 10.6, what release version shound install in order to work?

The project is not dependent on the Postgres version.

The error "Could not find or load main class net.twentyonesolutions.m2pg.PgMigrator" means that the classpath (or -cp) argument is not set properly.

Please post the java command that you are using, and where you execute it (working directory) with respect to the lib directory that ships with the project.

Hey there: Thanks for your response, I was able to bypass that. the error. Now the error i'm receiving is the following: Exception in thread "main" java.sql.SQLException: No suitable driver found for jdbc:sqlserver:172.16.4.17 My database in on a server. Thanks for any help on this matter.

That's because it can not find the JAR file with the driver for MSSQL. It should also be on the classpath, and the file that ships with the distribution is mssql-jdbc-6.2.2.jre8.jar so you can use that.

Hi Isapir

I got same error and my java command is like following. I can not see lib directory that you mentioned.
java -Dconnections.mssql.user=readonly -Dconnections.mssql.password=secret -cp "lib/*" net.twentyonesolutions.m2pg.PgMigrator ddl MsSqlAWT2Postgres.conf

Hi isapir,
lib directory is missing in the repository. Can you provide the compiled classes

How -cp should be setup right?
I see in from the root path where migrate.bat is executed there are two folders - 'examples' and 'src' (not lib). So I changed lib to src inside bat. Path to all java files are same, i.e. (from root) src/main/java/net/twentyonesolutions/m2pg yet on executing migrate.bat ddl I am getting
Error: Could not find or load main class net.twentyonesolutions.m2pg.PgMigrator
Just to simplify things I tryed inside dir with java files simply execute java PgMigrator.java. Yet same error came up.
All commands executed are with admin rights and variable path are set to java's lib and bin directories. I quess there is something simple I am missing. Any ideas?

Hi,

I am experiencing this issue and i am using the same command as mentioned in batch file

[Marius92]

I ran the application but apparently when it creates the tables it does not know how to add a foreign key. it's that correct? or the app should know how to handle the foreign keys? Thnak you!
