Downloads a Bazel repository as a compressed archive file, decompresses it,
and makes its targets available for binding.
It supports the following file extensions: `"zip"`, `"jar"`, `"war"`, `"aar"`, `"tar"`,
`"tar.gz"`, `"tgz"`, `"tar.xz"`, `"txz"`, `"tar.zst"`, `"tzst"`, `tar.bz2`, `"ar"`,
or `"deb"`.
Examples:
Suppose the current repository contains the source code for a chat program,
rooted at the directory `~/chat-app`. It needs to depend on an SSL library
which is available from http://example.com/openssl.zip. This `.zip` file
contains the following directory structure:
```
WORKSPACE
src/
openssl.cc
openssl.h
```
In the local repository, the user creates a `openssl.BUILD` file which
contains the following target definition:
```python
cc_library(
name = "openssl-lib",
srcs = ["src/openssl.cc"],
hdrs = ["src/openssl.h"],
)
```
Targets in the `~/chat-app` repository can depend on this target if the
following lines are added to `~/chat-app/WORKSPACE`:
```python
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
name = "my_ssl",
url = "http://example.com/openssl.zip",
sha256 = "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855",
build_file = "@//:openssl.BUILD",
)
```
Then targets would specify `@my_ssl//:openssl-lib` as a dependency.

String; optional

A directory prefix to strip from the extracted files.
Many archives contain a top-level directory that contains all of the useful
files in archive. Instead of needing to specify this prefix over and over
in the `build_file`, this field can be used to strip it from all of the
extracted files.
For example, suppose you are using `foo-lib-latest.zip`, which contains the
directory `foo-lib-1.2.3/` under which there is a `WORKSPACE` file and are
`src/`, `lib/`, and `test/` directories that contain the actual code you
wish to build. Specify `strip_prefix = "foo-lib-1.2.3"` to use the
`foo-lib-1.2.3` directory as your top-level directory.
Note that if there are files outside of this directory, they will be
discarded and inaccessible (e.g., a top-level license file). This includes
files/directories that start with the prefix but are not in the directory
(e.g., `foo-lib-1.2.3.release-notes`). If the specified prefix does not
match a directory in the archive, Bazel will return an error.

Targets would specify `@my_ssl//jar` as a dependency to depend on this jar.
You may also reference files on the current system (localhost) by using "file:///path/to/file"

<a href="https://bazel.build/versions/7.4.0/rules/lib/dict">Dictionary: String -> String</a>; required
<p>
A dictionary from local repository name to global repository name. This allows controls over workspace dependency resolution for dependencies of this repository.<p>For example, an entry `"@foo": "@bar"` declares that, for any time this repository depends on `@foo` (such as a dependency on `@foo//some:target`, it should actually resolve that dependency within globally-declared `@bar` (`@bar//some:target`).

<tr id="http_jar-sha256">
<td><code>sha256</code></td>
<td>
String; optional
<p>
The expected SHA-256 of the file downloaded.
This must match the SHA-256 of the file downloaded. _It is a security risk
to omit the SHA-256 as remote files can change._ At best omitting this
field will make your build non-hermetic. It is optional to make development
easier but either this attribute or `integrity` should be set before shipping.
</p>

<tr id="http_jar-url">
<td><code>url</code></td>
<td>
String; optional
<p>
A URL to a file that will be made available to Bazel.
This must be a file, http or https URL. Redirections are followed.
Authentication is not supported.
More flexibility can be achieved by the urls parameter that allows
to specify alternative URLs to fetch from.
The URL must end in `.jar`.
</p>
</td>
</tr>
<tr id="http_jar-urls">
<td><code>urls</code></td>
<td>
List of strings; optional
<p>
A list of URLs to a file that will be made available to Bazel.
Each entry must be a file, http or https URL. Redirections are followed.
Authentication is not supported.
URLs are tried in order until one succeeds, so you should list local mirrors first.
If all downloads fail, the rule will fail.
All URLs must end in `.jar`.
