License Report Generation
gradle license

Create a summary for all project dependency licenses. Right now just takes the Gradle-License-Report plugin output and cleans it up to a standardized JSON dictionary format and an HTML format.

Generate Gradle Dependencies

Generate a CSV report using Gradle-License-Report Plugin

Uses the jk1 fork of the plugin documented here

Configure Gradle Plugin

Add the following to the top of build.gradle (the plugins section must come before any other build.gradle statements)

plugins {
  id 'com.github.jk1.dependency-license-report' version '0.3.4'
import com.github.jk1.license.render.*
licenseReport {
    renderer = new CsvReportRenderer()
    configurations = ['compile']

Run the license report

gradle generateLicenseReport

Now you have a CSV report at build/reports/dependency-license/licenses.csv

Process Output to JSON

Convert to JSON and group up by normalized licenses.

I could have done this by modifying the Gradle plugin, but I also want to leave open the option of processing non-gradle output.

Run from the project folder. Will read in licenses.csv and output a licenses.json and license.html

JSON Output

  "BSD 3-Clause": [
      "name": "antlr:antlr",
      "version": "2.7.7"

      "version": "2.7.2"

HTML Output (to_html.js)

Takes the standardized JSON generated above and creates an HTML formatted report.
