[![docker-pulls](https://img.shields.io/docker/pulls/rockdrilla/woodpecker-sonatype-nexus)](https://hub.docker.com/r/rockdrilla/woodpecker-sonatype-nexus)
[![license](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)
Woodpecker CI plugin/standalone executable to publish artifacts to Sonatype Nexus.
Example `.woodpecker.yml`:
```yaml
steps:
- name: publish
image: rockdrilla/woodpecker-sonatype-nexus
settings:
url: https://nexus.domain.com
auth_base64:
# consult with #3406 for that syntax
# ref: https://github.com/woodpecker-ci/woodpecker/pull/3406
from_secret: nexus-auth-b64
upload:
- repository: project-apt
paths:
- dist/all/*.deb
- dist/amd64/*.deb
- repository: project-raw
paths:
- dist/raw/all-in-one.tar.xz
# property from upload specification for "raw" repository
directory: /build/
- repository: project-r
paths:
- dist/r/*.tar.gz
# property from upload specification for "r" repository
pathId: /src/contrib/
```
Example `.gitlab-ci.yml`:
```yaml
publish R:
stage: publish
image: rockdrilla/woodpecker-sonatype-nexus
variables:
NEXUS_URL: https://nexus.domain.com
#NEXUS_AUTH_BASE64 is stored as CI variable
NEXUS_REPOSITORY: project-r
NEXUS_PATHS: "dist/r/*.tar.gz"
NEXUS_PROPERTIES: "pathId=/src/contrib/"
```
Example manual invocation (within `rockdrilla/woodpecker-sonatype-nexus` container):
```sh
# publish R
publish-nexus \
--nexus.url https://nexus.domain.com \
--nexus.auth 'upload-user:super-$ecret-passw0rd' \
--nexus.repository project-r \
--nexus.paths 'dist/r/*.tar.gz' \
--nexus.properties 'pathId=/src/contrib/'
```
## Woodpecker CI plugin
Plugin documentation is provided in [separate document](./docs.md).
## Other CI systems / standalone executable
### Environment
| Environment variable | Required | Description |
|----------------------|----------|---------------------------------------------------------------------------------------------------|
| `NEXUS_URL` | **yes** | Sonatype Nexus URL (e.g. `https://nexus.domain.com`) |
| `NEXUS_AUTH` | *no* \* | HTTP Basic Authentication (plain-text, in form `{username}:{password}`) |
| `NEXUS_AUTH_BASE64` | *no* \* | HTTP Basic Authentication (base64-encoded) |
| `NEXUS_AUTH_HEADER` | *no* \* | generic HTTP authentication header (in form `{Header}={Value}`) |
| `NEXUS_REPOSITORY` | **yes** | Repository name (of type "hosted") |
| `NEXUS_PATHS` | **yes** | Comma-separated list of files to upload (accepts [globs](https://pkg.go.dev/path/filepath#Match)) |
| `NEXUS_PROPERTIES` | *no* | Comma-separated list of additional repository-specific properties (in form `{key}={value}`) |
### Command-line flags
| Flag | Required | Multiple times? | Description |
|-----------------------|----------|-----------------|-----------------------------------------------------------------------------------|
| `--nexus.url` | **yes** | *no* | Sonatype Nexus URL (e.g. `https://nexus.domain.com`) |
| `--nexus.auth` | *no* \* | *no* | HTTP Basic Authentication (plain-text, in form `{username}:{password}`) |
| `--nexus.auth.base64` | *no* \* | *no* | HTTP Basic Authentication (base64-encoded) |
| `--nexus.auth.header` | *no* \* | *no* | generic HTTP authentication header (in form `{Header}={Value}`) |
| `--nexus.repository` | **yes** | *no* | Repository name (of type "hosted") |
| `--nexus.paths` | **yes** | **yes** | List of files to upload (accepts [globs](https://pkg.go.dev/path/filepath#Match)) |
| `--nexus.properties` | *no* | **yes** | Additional repository-specific properties (in form `{key}={value}`) |
## Notes
- At least one authentication setting **must** be provided.
If there are more than one setting were specified then setting is selected in order of priority (from most to least):
- `NEXUS_AUTH_HEADER`
- `NEXUS_AUTH_BASE64`
- `NEXUS_AUTH`
- Preferred setting for HTTP Basic Authentication is `NEXUS_AUTH_BASE64` as there is minimal chance for breaking value during serialization/deserialization.
- Generic authentication setting `NEXUS_AUTH_HEADER` is provided for cases where authentication differs from HTTP Basic Authentication.
- The one may use [User Tokens](https://help.sonatype.com/en/user-tokens.html) for HTTP Basic Authentication.
There is no need for special handling as tokens are conform to scheme:
`{token name code}:{token pass code}`
- The one may consult with Sonatype Nexus REST API for repository-specific properties for component uploads.
Sonatype Nexus REST API is available via:
- Web UI - `https://nexus.domain.com/#admin/system/api`
- Swagger - `https://nexus.domain.com/service/rest/swagger.json`
Points of interest are:
- `/v1/formats/upload-specs`
- `/v1/components` (with `POST` method)
Also, there is [fallback upload spec](./nexus/upload_spec/fallback.go):
- if component/asset field does not specify `Optional: true` then this field is **required**.
## Known limitations
- No more than 32 assets may be uploaded at once (if destination repository type supports multiple upload).
This is (merely) artificial limit for **single** upload - plugin will upload all listed files but via several calls.
If you suppose that Sonatype Nexus is viable to receive more assets at once - feel free to contact me.

Woodpecker CI plugin to publish artifacts to Sonatype Nexus.
## Settings
| Name | Required | Default value | Description |
|---------------|----------|---------------|-------------------------------------------------------------------------|
| `url` | **yes** | *none* | Sonatype Nexus URL (e.g. `https://nexus.domain.com`) |
| `auth` | *no* \* | *none* | HTTP Basic Authentication (plain-text, in form `{username}:{password}`) |
| `auth.base64` | *no* \* | *none* | HTTP Basic Authentication (base64-encoded) |
| `auth.header` | *no* \* | *none* | generic HTTP authentication header (in form `{Header}={Value}`) |
| `upload` | **yes** | `[]` | List of upload rules (JSON array, see below) |
**Notes:**
- At least one authentication setting **must** be provided.
If there are more than one setting were specified then setting is selected in order of priority (from most to least):
- `auth.header`
- `auth.base64`
- `auth`
- Setting names above are "short" variants.
Full-qualified setting name looks like "`nexus.{short_name}`"
and has higher priority if short variant is specified too.
- Dots in setting names are NOT mandatory.
The one may replace dots ("`.`") with hyphens ("`-`") or underscores ("`_`").
### Upload settings
`upload` list consists of elements with following properties:
| Name | Required | Default value | Description |
|---------------|----------|---------------|-----------------------------------------------------------------------------------|
| `repository` | **yes** | *none* | Repository name (of type "hosted") |
| `paths` | **yes** | *none* | List of files to upload (accepts [globs](https://pkg.go.dev/path/filepath#Match)) |
Additional (repository-specific) properties may be specified right with settings specified above.
## Example
```yaml
steps:
- name: publish
image: rockdrilla/woodpecker-sonatype-nexus
settings:
url: https://nexus.domain.com
auth.base64:
from_secret: nexus-auth-b64
upload:
- repository: project-apt
paths:
- dist/all/*.deb
- dist/amd64/*.deb
- repository: project-raw
paths:
- dist/raw/all-in-one.tar.xz
# property from upload specification for "raw" repository
directory: /build/
- repository: project-r
paths:
- dist/r/*.tar.gz
# property from upload specification for "r" repository
pathId: /src/contrib/
```
