The IntelliJ cannot find the mysql-connector-java dependency and hits error "unknown was not found"?
pom.xml
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
Terminal
mysql:mysql-connector-java:jar:unknown was not found in https://repo.maven.apache.org/maven2
during a previous attempt.
This failure was cached in the local repository and resolution is not reattempted until the
update interval of central has elapsed or updates are forced
Solution
Replace the old MySQL JDBC mysql-connector-java dependency with this mysql-connector-j dependency.
pom.xml
<dependency>
<groupId>com.mysql</groupId>
<artifactId>mysql-connector-j</artifactId>
<scope>runtime</scope>
</dependency>
Thank you so much! No where I found this solution.
