Ability to download buildpacks

[DonBower]

I would like to be able to list all the versions of all the buildpacks, and then be able to select specific buildpacks and download them.

We have created an issue in Pivotal Tracker to manage this:

The labels on this github issue will be updated when the story is started.

Hi Dan, We would love to understand your scenario better! Could you give us an example of how you'd like to use it?

Hi @kartiklunkad26,

I have the same question:

$ ./pivnet-darwin-amd64-0.0.50 product -p buildpacks
+----+------------+--------------------+
| ID |    SLUG    |        NAME        |
+----+------------+--------------------+
| 69 | buildpacks | Buildpacks for PCF |
+----+------------+--------------------+
$ ./pivnet-darwin-amd64-0.0.50 releases -p buildpacks | grep "Java Buildpack 4.11"
| 84771 | Java Buildpack 4.11        | This release focuses on        | 2018-04-18T13:03:15.148Z |
$ ./pivnet-darwin-amd64-0.0.50 download-product-files -p buidldpacks -r "Java Buildpack" -i 84771
Pivnet error: could not find product with 'id' or 'slug'=buidldpacks
$ ./pivnet-darwin-amd64-0.0.50 download-product-files -p buidldpacks -r 84771
Must provide either globs or product file IDs

I want to use the CLI to download Java Buildpack 4.11. How does one accomplish that?

@mhottinger1 in the snippet you just posted you have a typo in -p buildpacks. Do you get the same issue when you fix that typo?

[mhottinger1]

@robdimsdale, nice catch thank you --

Here's my latest attempt:

$ ./pivnet-darwin-amd64-0.0.50 download-product-files -p buildpacks -r "Java Buildpack 4.11" -i 84771
No product files found for ids: [84771] or globs: []

[robdimsdale]

@mhottinger1 I think the issue is that 84771 is the ID of the release, not the product file.

2018-04-13 10:26:23 ~ → pivnet product-files -p buildpacks -r 'Java Buildpack 4.11'
+--------+--------------------------+--------------+-----------------------------------------------------------+
|   ID   |           NAME           | FILE VERSION |                      AWS OBJECT KEY                       |
+--------+--------------------------+--------------+-----------------------------------------------------------+
| 121586 | Java Buildpack           |         4.11 | product-files/buildpacks/java-buildpack-v4.11.zip         |
| 121585 | Java Buildpack (offline) |         4.11 | product-files/buildpacks/java-buildpack-offline-v4.11.zip |
+--------+--------------------------+--------------+-----------------------------------------------------------+

When I try with the product file ID I get the following:

2018-04-13 10:26:23 ~ → pivnet download-product-files -p buildpacks -r 'Java Buildpack 4.11' -i '121586'
2018/04/27 14:01:02 Downloading 'java-buildpack-v4.11.zip' to 'java-buildpack-v4.11.zip'

[robdimsdale]

Also, you could use globs instead, e.g.:

2018-04-13 10:26:23 ~ → pivnet download-product-files -p buildpacks -r 'Java Buildpack 4.11' -g '*offline*.zip'
2018/04/27 14:03:26 Downloading 'java-buildpack-offline-v4.11.zip' to 'java-buildpack-offline-v4.11.zip'

This type of thing would be relatively easy to script and iterate over multiple buildpacks - answering the origina question from @DonBower, too.

[mhottinger1]

Good stuff @robdimsdale! From a UX perspective it wasn't clear to me how to use the -g flag while the other flags were relatively easy to figure out. Being able to specify a basic glob regex makes it easier in that there's no need to find the product file identifier.

On a side note, I noticed that Java uses an offline glob pattern some of the others I checked including NodeJS, Ruby, and Staticfile all use cached glob pattern. Just something for others to be aware of.
