Apache Commons Daemon software is a set of utilities and Java support
    classes for running Java applications as server processes. These are
    commonly known as 'daemon' processes in Unix terminology (hence the
    name). On Windows they are called 'services'.

Documentation
-------------

More information can be found on the [Apache Commons Daemon homepage](https://commons.apache.org/proper/commons-daemon).
The [Javadoc](https://commons.apache.org/proper/commons-daemon/apidocs) can be browsed.
Questions related to the usage of Apache Commons Daemon should be posted to the [user mailing list](https://commons.apache.org/mail-lists.html).

Getting the latest release
--------------------------
You can download source and binaries from our [download page](https://commons.apache.org/proper/commons-daemon/download_daemon.cgi).

Alternatively, you can pull it from  the central Maven repositories:

```xml
<dependency>
  <groupId>commons-daemon</groupId>
  <artifactId>commons-daemon</artifactId>
  <version>1.4.1</version>
</dependency>
```

Building
--------

Building requires a Java JDK and [Apache Maven](https://maven.apache.org/). 
The required Java version is found in the `pom.xml` as the `maven.compiler.source` property.

From a command shell, run `mvn` without arguments to invoke the default Maven goal to run all tests and checks.

Contributing
------------

We accept Pull Requests via GitHub. The [developer mailing list](https://commons.apache.org/mail-lists.html) is the main channel of communication for contributors.
There are some guidelines which will make applying PRs easier for us:
+ No tabs! Please use spaces for indentation.
+ Respect the existing code style for each file.
+ Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
+ Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running ```mvn```.

If you plan to contribute on a regular basis, please consider filing a [contributor license agreement](https://www.apache.org/licenses/#clas).
You can learn more about contributing via GitHub in our [contribution guidelines](CONTRIBUTING.md).
