Does anyone know if it is possible to have a group of jars on disk and that the java projects access it as a reference, without having to include them in the project itself, and thus make it lighter ?. They told me that it was possible to add in the classpath of the pc, but sincerely I never heard or seen something like that.
Yes it is possible. For example, you can have the following structure on your disk (assuming * -nix systems):
/opt
- /carlos
- /comun
+ lib1.jar
- /apps
+ miapp.jar
Then, your application could be executed from a terminal with the following steps:
$ cd /opt/carlos/apps
$ java -cp .:/opt/carlos/comun/lib1.jar -jar miapp.jar com.paquete.principal.ClasePrincipal
The same example above but for Windows:
C:\opt
- \carlos
- \comun
+ lib1.jar
- \apps
+ miapp.jar
Command:
$ C:
$ cd C:\opt\carlos\apps
$ java -cp .;C:\opt\carlos\comun\lib1.jar -jar miapp.jar com.paquete.principal.ClasePrincipal
