The problem was: If you declare too many dependencies wich are the same but different to the version, then delete the folder: .m2/reporsytory/org/springframework.

Then start Eclipse and klick on your prject folder : --> maven --> project update.

Then eclipse loads the nessesery necessary dependencies.

If it doesnt work, then uninstall eclipse completely.
delete all eclipse-files and folders (but you can save your project-folder)

Then reinstall eclipse.

It worked fine for me.

Hi community!

Yes, it looks like a simple problem, but it isnt and i think I'm getting insane.

I get this following error-message with Eclipse and Spring Tool Suite:

I've done the following steps: 1.: Klick on project --> properties --> Deployment Assembly -> Add ->  Java Build Path Entries -> Maven Demepndencies -> Finish.
2.: mvn install and mvn build.

The problem was that spring-jdbc 3.0.3.RELEASE was required.
But i used spring-jdbc 5.0.3 RELEASE. So, obviously the classes org.springframework.jdbc.core.simple.ParameterizedRowMapper and org.springframework.jdbc.core.simple.SimpleJdbcTemplate were no longer supported in spring 5.0.3 framework.

Hi community!

My eclipse-IDE shows me, that the " import org.springframework.jdbc.core.simple.SimpleJdbcTemplate and import org.springframework.jdbc.core.simple.ParameterizedRowMapper" are missing.
But I have already installed the required dependencies "spring-boot-starter-jdbc , spring-jdbc and spring-dao"

I hope you can help me!

Thanks a lot

I've found a great book to start with!

But I think it's only in a german-edition available.

It's called: "Spring 2 für Grünschnäbel" It's an open-book and free to download!
