You have to pull down the source and build it yourself. It appears that no artifacts have been deployed to Maven Central or the Apache snapshots repository.

FWIW, there hasn't been any significant development on that code since May 2015.

Maven will help you figure this out. I'm not a maven expert, so there might be a better way to do this, but I did it this way. Create a subdir somewhere (/tmp/blah for instance). And create pom.xml in that directory that looks like this:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mycompany.app</groupId>
  <artifactId>my-app</artifactId>
  <packaging>jar</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>my-app</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-text</artifactId>
        <version>1.4</version>
    </dependency>
  </dependencies>
</project>

Then from that directory, ask maven with:

mvn dependency:tree

You'll get a ton of output, but at the end, this is all you end up with:

[INFO] com.mycompany.app:my-app:jar:1.0-SNAPSHOT
[INFO] \- org.apache.commons:commons-text:jar:1.4:compile
[INFO]    \- org.apache.commons:commons-lang3:jar:3.7:compile

That should be the complete list -- your project requires apache commons text, and that project requires commons lang3.
