Apache Commons Lang, a package of Java utility classes for the
classes that are in java.lang's hierarchy, or are considered to be so
standard as to justify existence in java.lang.
The code is tested using the latest revision of the JDK for supported
LTS releases: 8, 11, 17 and 21 currently.
See https://github.com/apache/commons-lang/blob/master/.github/workflows/maven.yml
Please ensure your build environment is up-to-date and kindly report any build issues.
Documentation
-------------
More information can be found on the [Apache Commons Lang homepage](https://commons.apache.org/proper/commons-lang).
The [Javadoc](https://commons.apache.org/proper/commons-lang/apidocs) can be browsed.
Questions related to the usage of Apache Commons Lang 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-lang/download_lang.cgi).
Alternatively, you can pull it from the central Maven repositories:
```xml
org.apache.commons
commons-lang3

```
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`.
+ Before you pushing a PR, run `mvn` (by itself), this runs the default goal, which contains all build checks.
+ To see the code coverage report, regardless of coverage failures, run `mvn clean site -Dcommons.jacoco.haltOnFailure=false`
If you plan to contribute on a regular basis, please consider filing a [contributor license agreement](https://www.apache.org/licenses/#clas).
