[Question] Maven-Plugin - Don't find/execute cypher script

[Raf23]

Hi,

For a project in Bosa we need to migrate data from GDPR project V1 to V2 (with different shape of data)

We would like to use neo4j-migration.

We are testing the CLI and it works perfectly !

For the usage of maven-plugin we have a problem:

• nothing is executed (the connexion to the DB is OK).
• it's like the cypher queries are not found
• Maybe an issue with the path ?

Kind regards,

Raphaël

Hello @Raf23 thanks for using this project and reaching out. The reason no migrations are found in you scenario is that the plugin looks by default in the target folder, so your project must be compiled and resources be processed before the plugin. The migrate goal binds by default to the pre-integration-test phase, so that is normally done at this point in time.

Please have a look at the following quick video, it's easier than typing it all down:

Here's the project from the vid (I hope the quality improves when YT has processed it)

migrations-maven-plugin.zip

mvn clean process-resources neo4j-migrations:info 

prints:

Hello @michael-simons ,

Thanks for all your informations.

All scripts are well in the target folder (even with your project).

I though the issue was related to windows path... I try to change the path with locationToScan in my pom but without success.

I've put up a pull request to add @Raf23! :tada:

[michael-simons]

Thank you your perseverance and patience! This is indeed a bug. I don't have a windows machine, and these are hard to tackle. Would you be able to try out a snapshot or shall I ping you here next week when I put out a patch?

[Raf23]

Hi Michael,

No issue, I'm currently not blocked because I'm using the CLI Yes I can test a snapshot for the plugin maven.

Let me know when I can try.

Kind regards,

Raphaël

1.15.2 has just been released and should hit central soon. It's a bit easier with the dependencies of the plugin to just include that.

2.0.2 will follow shortly.

I hope this fixes the issue. Thanks again, Raphaël.
