I Couldn't install geany-plugin-gdb in jessie.

Hi,
refering to

https://packages.debian.org/search?lang=en&suite=all&searchon=names&keywords=geany-plugin-gdb

I added the line
deb http://ftp.jp.debian.org/debian/ wheezy main
to /etc/apt/sources.list, and apt-get updated,
but I was not able to install geany-plugin-gdb.

$ sudo apt-get install geany-plugin-gdb

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
geany-plugin-gdb : Depends: geany-plugins-common (= 0.21.1.dfsg-4) but
1.24+dfsg-5 is to be installed
E: Unable to correct problems, you have held broken packages.

What should I do?
And why isn't geany-plugin-gdb in the jessie repository?
