maven setting of version of protocol buffer

[yiyu jia <ji...@gmail.com>]

Hi,

I noticed that I always get error message which says there is no
Parser.class found in protocbuffer. Aftter checking, I found that is
because there is no version info about protocbuff in POM file. So, Maven
always try to download old version of protocbuffer though I build the
lastest one and install it in local maven repository already. And the
default version Maven downloaded has no Parser.class .

I solve the issue by adding version info of protocbuffer in POM files.
However, I think there should be a better way to solve this. anybody can
show me how to get reqired version of protocbuff without changing POM files?

thanks and reggards,

Yiyu

Hi Colin,

Yes. What I talked about is google protobuf. What I did is just open each
POM files that has protobuf dependency and add the version number I
installed into my local repository.

I guess other developers have no problem because they use there internal
maven repository, which contains right version of protobuf. for my case, I
build hadoop common in my home pc and it linked to a public respository,
which has old version of protobuf having no Parser.java.

I see many dependencies has no version tag specified in the source code
tree. I guess it was done purposely? Maybe somebody can explain why we do
not specify the version in each dependency declaration.

thanks and regards,

yiyu

Hi Yiyu,

Are you referring to com.google.protobuf?

We generally do depend on specific versions of jars in the pom.xml files,
to prevent exactly this sort of problem.  If you have a patch which adds
this, you should post it.  It might help someone else.

cheers,
Colin
