Programming from 51 years old (currently 52) Note: Add jar with VScode Class.forName java.lang.ClassNotFoundException: com.mysql.cj.jdbc.Drive
When I java with VScode, I sometimes get hooked. This time, I wanted to use jdbc of mysql to handle DB (mysql).
java.long.ClassNotFoundException: com.mysql.cj.jdbc.Driver
I couldn't stop the error. A full day to resolve (tears)
In VScode, the [java Dependency Viewer] is used to install the external jar file, so when installing [Project Manager for java] with the VScode extension (for jdk8, the instool version is 0.9.0 or older. Please use it).
Then, the following memorandum!
Select the java file in ①
Select ② Explorer menu [...]
③ If jdk8-> [java Dependencies]
For jdk11-> [java Project]
If you check
Like ④ [Java PROJECTS] \ (jdk11) or [Java DEPANDENCIES] \ (jdk8)
Is displayed, open those directories
Display [Referenced Libraries]
Click [+] in ⑤!
Then
Since the folder opens so that you can specify the external file you want to use
Specify the desired file and finish!
How is it! It took time!
