I am using IntelliJ IDEA,and I want to configure MySQL database from the IDE:
then fail:
The error is:
Failed to download 'http://download.jetbrains.com/idea/jdbc-drivers/mysql-connector-java-5.1.40-bin.jar
I don't know why connection will time out.
I can download other things such as plugins from jetbrains, but except jdbc-drivers.
I recommend taking a look in IDEA's log files to see if they may have additional details as to why the download is timing out. From the menu go to Help > Show log.
As a workaround, you can manually download the drivers and place them in the necessary location. Download bo the JAR and the mysql-connector-license.txt license file (from http://download.jetbrains.com/idea/jdbc-drivers/mysql-connector-license.txt of from MySQL directly). Place both files in the path {idea-config-dir}/jdbc-drivers/MySQL Connector/J/5.1.40 (modifying the version number if necessary). The location of the {idea-config-dir} can be looked up in the Directories used by the IDE to store settings, caches, plugins and logs help document. For example, c:\Users\Dilbert\.IntelliJIdea2017\config or ~/Library/Preferences/IntelliJIdea2017
Thus, in the end, that directory should have two files:
mysql-connector-java-5.1.40-bin.jarmysql-connector-license.txtput jars in
C:\Users\UUSER\AppData\Roaming\JetBrains\DataGrip2020.1\jdbc-drivers\PostgreSQL\42.2.5
from another install with internet
In 2019, The folder is this >>
C:\Users{YourUser}.DataGrip2019.3\config\jdbc-drivers\MySQL Connector\J 8\8.0.21
Download jar from https://repo1.maven.org/maven2/mysql/mysql-connector-java/8.0.21/mysql-connector-java-8.0.21.jar
