Not Read class from project and external dependencies

[SKTT1. Faker, geändert vor 7 Jahren.]

I defined gradle:
compile group: 'mysql', name: 'mysql-connector-java', version: '6.0.2'

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver cannot be found by adddatabase_1.0.0

Just adding a compile dependency does not mean it will, in turn, be a runtime dependency.

But you're in luck, I have a blog for that: https://web.liferay.com/web/26526/blog/-/blogs/osgi-module-dependencies

I try it. but it 's not working.
.gradle: runtime group: 'mysql', name: 'mysql-connector-java', version: '6.0.2'

.bnd: Include-Resource: @mysql-connector-java-6.0.2.jar
Bundle-ClassPath:\
.,\
lib/mysql-connector-java.jar
-includeresource:\
lib/mysql-connector-java.jar=mysql-connector-java-6.0.2.jar
Some class i can use them, but class Driver I can not use it.

That's a different issue. That's due to missing dependencies which I covered here: https://web.liferay.com/web/26526/blog/-/blogs/osgi-module-dependencies

Honestly I think you're better served putting the JDBC jars in the lib/ext folder so they are globally available, but it's up to you.
