Hi,

We are trying to install lfs-plugin in our gerrit instance which has version "2.13.1"

we tried downloading plugin in below link :

https://gerrit-ci.gerritforge.com/job/plugin-lfs-master/19/

But, when we download and check the plugin is not installed, error log says below:

[root@<server> logs]# cat error_log |grep lfs

[2016-10-17 07:31:22,745] [PluginScanner] WARN com.google.gerrit.server.plugins.PluginLoader : Cannot load plugin lfs

Hi Ashwiki,

are you using JDK 7 or 8?

Hi Luca,

Thanks for the reply, we are using JDK 7.x

OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

Thanks

Ohhh yes, found the issue then.

The jenkins slaves we used on Gerrit CI have JDK 8 enabled by default.

I've pushed a change recently to switch to JDK 7 according to the .buckconfig settings, but old builds were using a Java 8 bytecode.

You have downloaded a master build of the plugin and *then* it is compiled with the same JDK level required by Gerrit master: Java 8.

When [1] will be merged, you will have as well the stable-2.13 version of the plugin, which will be built using JDK level 7, the same one used by Gerrit.

In the meantime ... bear with us, or you can build the plugin yourself :-)

Luca.

There you go:

https://gerrit-ci.gerritforge.com/view/Plugins-2.13/job/plugin-lfs-stable-2.13/

It is JDK 7 byte-code.

Hi,

Thank you for your suggestion.

But it looks like our configuration is not correct. When tried with http protocol, got the below error.

Could you please let us know if our configuration is not correct.

Hi Matthias,

Thank you for providing the link. We have configured the projects to use LFS as below.

We have added a lfs.config file on refs/meta/config branch of ALL-Projects. And in Global level, we have configured /xx/xx/etc/gerrit.config file as below.

But still getting the same error:( Could you please help us in solving this.

lfs.config file on refs/meta/config of ALL-Projects:

[lfs "check_lfs/*"]

enabled = true

maxObjectSize = 1000m

[root@server gerrit]# cat etc/lfs.config

[lfs "check_lfs/*"]

enabled = true

maxObjectSize = 1000m

[root@server gerrit]# cat etc/gerrit.config |grep lfs

[lfs]

plugin = lfs

[root@server1 check_lfs]# git push origin master

I think "check_lfs" doesn't match "check_lfs/*" configured in lfs.config in refs/meta/config branch.

Try this

[lfs "check_lfs"]

enabled = true

maxObjectSize = 1000m
