Met unexpected error when uploading and installing add-on (Bamboo)
Asked by Rui Hu:

Hi all,

I tried to upload a jar file for adding a new add-on in bamboo. And it reports unexpected error after clicking 'upload' button. In the meantime, the pop-up windows which shows installing the add-on cannot be closed.

The add-on jar file is from <https://marketplace.atlassian.com/download/plugins/com.thed.zephyr.zfj-bamboo/version/10000020>

Anyone know how to solve this ?

Thanks,

Rui

I tried and waited for over 1 hour. After refresh the page, it still failed.

body: I have encountered this error when Bamboo's *Base URL* setting does not match the actual URL in use, refer to [Specifying Bamboo's URL](https://confluence.atlassian.com/bamboo/specifying-bamboo-s-url-289277242.html) on how to address this in case:
> **To specify Bamboo's URL:**
>
> 1. Click the ![](https://confluence.atlassian.com/bamboo/files/306350223/405504149/1/1379633820512/cog.png) icon in the Bamboo header and choose **Overview**.
> 2. Click **General Configuration** (under 'System'), in the left navigation panel.
> 3. In the **Base URL** field, type the URL address of your Bamboo server (for example, "<http://keg:8080/bamboo>").
> 4. Click **Save**.

The error is slightly misleading, insofar the add-on installation continues (and usually succeeds), but he client side add-on installation progress monitoring is unable to communicate with Bamboo via the erroneous base URL.

body: Thank you Steffen.

I checked the URL and it is correct.

I tried again but failed again.

body: In this case it's probably going to be most efficient if you directly contact the add-on's vendor Zephyr via the [Get support](http://support.yourzephyr.com/) link from the add-on listing. I have also added the resp. tag 'addon-com.thed.zephyr.zfj-bamboo' to your question, but given you are the first to ask about it, they likely won't monitor this yet.

body: I cannot upgrade "Support Tools Plugin" either.

And I tried to install "TFS Repository" but shows "Problem accessing the file TFS Repository."

I think there's something wrong which may not the Zephyr's problem.

But I will try to contact Zephyr support team. Thank you.

body: [Bamboo 5.14](https://confluence.atlassian.com/bamboo/bamboo-5-14-release-notes-856821277.html) comes with a few [API changes for 5.14](https://developer.atlassian.com/bamboodev/bamboo-api-changes-by-version/changes-for-5-14) that some add-ons likely need to address before they will be compatible again:
> Plugins that are particularly prone to incompatibilities and require special attention are those that deal with:
>
> * automatic plan creation and management
> * automatic plan branch creation and management
> * repository configuration management

From that angle, the "TFS Repository" issues might actually be expected, but I wouldn't have expected issues with Zephyr's add-on, nor with the "Support Tools Plugin", which are concerned with entirely different topics in principle.
