This plugin provides a task to generate a HTML license report based on the
configuration. (eg. licenseDebugReport for all debug dependencies in an Android project).
Applying this to an Android or Java project will generate a the license
file(open_source_licenses.html) in the <project>/build/reports/licenses/.
Also, for Android projects the license HTML file will be copied to <project>/src/main/assets/.

Generates a HTML report of the all open source licenses. (eg. licenseDebugReport for all debug dependencies in an Android project).
Example build.gradle:
dependencies {
implementation 'com.android.support:design:26.1.0'
implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.3'
implementation 'wsdl4j:wsdl4j:1.5.1' // Very old library with no license info available

Other missing information is provided as default values that can be corrected from other sources. Projects are grouped by license name - the licence text is only provided once. Projects with multiple licenses are grouped as if those licenses were a single combined license.

]Note, if no license information is found for a component, the licenses element in the JSON output will be an empty array.
The plugin can be configured to generate specific reports and automatically copy the reports to the assets directory (Android projects only). The default behaviours are:
- Java projects: Generate both the HTML report and the JSON report.
- Android projects: Generate both the HTML report and the JSON report, and copy the HTML report to the assets directory.
To override the defaults, add the licenseReport configuration closure to the build script.
apply plugin: "com.jaredsburrows.license"
licenseReport {
generateHtmlReport = false
generateJsonReport = true
// These options are ignored for Java projects
copyHtmlReportToAssets = true
copyJsonReportToAssets = false
}The copyHtmlReportToAssets option in the above example would have no effect since the HTML report is disabled.
