Apache Commons Lang v3 Source Code Files
Apache Commons Lang 3 is the 3rd version of Apache Commons Lang, which provides a host of helper utilities for the java.lang API.
Apache Commons Lang 3 Source Code files are provided in both binary packge (commons-lang3-3.12.0-bin.zip) and source package (commons-lang3-3.12.0-src.zip). You can download them at Apache Commons Lang Website.
Apache Commons Lang 3 Source Code has no dependencies and is compatible with Java 8 and newer versions. You can compile it to generate your own version of Apache Commons Lang 3 JAR file.
