Deployed in Tomcat to report an error：Required dependency org.apache.httpcomponents:httpclient is not installed

[DaLiangLee]

.182
Tomcat 8
I used Tomcat to run successfully on my windows 10 before, but it failed on windows server 16. I need your help very much now, thank you

Make sure your system has an outgoing internet connection, otherwise plugins with additional dependencies can not be installed even if uploaded from local. If you are sure your outgoing connection is properly working, it may be that either http://www.google.com (for the initial check) or the Maven repository (for dependencies) are temporarily not reachable. In that case, you have to repeat the whole setup procedure. There is already a feature request for a retry button to manage this case more conveniently: #942.

I am using a local plug-in...

确保您的系统具有互联网连接，否则，即使从本地上传，也无法安装具有其他依赖性的插件。如果您确定传出连接正常工作，则可能暂时无法访问http://www.google.com（用于初始检查）或Maven存储库（用于依赖项）。在这种情况下，您必须重复整个设置过程。已经有功能要求重试按钮以更方便地管理这种情况：[＃942](https://github.com/opensourceBIM/BIMserver/issues/942)。

Please do not post content in Chinese.

I understood that you installed the plugin from a local file. But if the plugin has additional dependencies, then it still needs an outgoing internet connection.

In the BIMvie.ws case however, there shouldn't be any additional dependencies. BIMvie.ws declares only a dependency that's in your BIMserver installation anyway and such dependencies should be skipped during plugin installation. Apparently they are not and that might be a bug due to local installations not being recommended and well-supported. In your previous setup, you may have had an internet connection at some point and those dependencies where then cached in your local Maven repository. Now you are lacking some of those dependencies.

If you can, I recommend to do the initial setup including plugin installation with an internet connection. You can work disconnected afterwards.

Our server cannot access google...
I copied the local Tomcat folder to my server, and this error occurred.

Is an Internet connection required at this time? The error message he reported does not seem to be this. I'm in C#, I can't understand this.

Thank you very much for your reply.

[DaLiangLee]

When the server can access google...

[DaLiangLee]

Repackage, change google.com to something else, and the progress has been like this...

[DaLiangLee]

Half an hour after...

I think this is a very good open source project, but it is always a strange problem when installing, and each computer encounters a different problem. . .

[DaLiangLee]

Still did not succeed

Thanks for the additional detail, though please don't use screenshots for console output, log files etc. next time.

I can't see the bottom of your last screenshot, but actually, with the error in the console, there should be an error in the setup screen in your browser as well. Definitely you should not see a message of successful setup finished? Then, subsequently, as the plugin has was not successfully installed (namely missing its dependencies), it can not be loaded, when you start the server.

There is something weird about your internet access. Don't you see 4.5.7 in the version list of org.apache.httpcomponents:httpclient at Maven central? Or at repo.maven.apache.org? Maybe you are seeing outdated versions at those URLs?

I have added a check to skip Maven dependency resolution for dependencies provided by BIMserver. This will mitigate the issue for bimvie.ws which only declares a dependency on pluginbase and some other similar cases. However, once you try to install plugins with additional dependencies, such as ifcplugins without internet connection, you'll hit the same issue again.

As an enhancement, we could install all dependencies that BIMserver contains anyway into the local Maven repository on Jar expansion or War initialization. This would allow local install of all plugins that do not require additional dependencies beyond that. I'll keep this as a feature request.

As a workaround, if you have a backup of your old server setup, you could try to copy the local Maven repository to your new server.

[DaLiangLee]

After you modify the code, we immediately packaged it, and now it's successful deploed!
Thank you so much for your help!

[hlg]

Good to hear that.

The error you've shown should not have appeared with internet access enabled. To help track down the issue for future cases, can you please confirm whether you can or cannot see 4.5.7 in the version list of org.apache.httpcomponents:httpclient at Maven central and at repo1.maven.org from the server where you deployed BIMserver? Thank you very much!
