One secret is required for decrypting the GPG Key with which the PMD Releases are signed and
for a ssh key, which is used to copy files to sourceforge.
## Environment variables
* `PMD_CI_SECRET_PASSPHRASE`
* `CI_DEPLOY_PASSWORD`
* `CI_SIGN_PASSPHRASE`

## Known Issues
Intermittent build failures while downloading dependencies from maven central.
Root issue seems to be SNAT configs in Azure, which closes long running TCP connections
only on one side: https://docs.microsoft.com/en-us/azure/load-balancer/troubleshoot-outbound-connection#idletimeout
The default timeout is 4 minutes.
Workaround as described in https://github.com/actions/virtual-environments/issues/1499 and
https://issues.apache.org/jira/browse/WAGON-545 is applied:
`-Dmaven.wagon.httpconnectionManager.ttlSeconds=180 -Dmaven.wagon.http.retryHandler.count=3`

## Hints
### Remote debugging
Debugging remotely is possible with <https://github.com/mxschmitt/action-tmate>.
Just add the following step into the job:
```
- name: Setup tmate session
uses: mxschmitt/action-tmate@v3
```
Note: This is dangerous for push builds, because these have access to the secrets and the SSH session
is not protected.
### Local tests
You can run a local instance with docker:
```
docker run -it --mount type=bind,source=path/to/pmd,target=/workspaces/pmd/pmd ubuntu:latest
```
You'll need to install a few packages before you can start... You can verify with `check-environment.sh`
if everything is prepared.
