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 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

Projects with multiple licenses are grouped as if those licenses were a single combined license.

Notice for packages
Android GIF Drawable Library (1.2.3) - The MIT License
Views and Drawable for displaying animated GIFs for Android
https://github.com/koral--/android-gif-drawable
design (26.1.0) - The Apache Software License
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 HTML, JSON and CSV reports.
- Android projects: Generate HTML, JSON and CSV reports, and copy the HTML report to the assets directory.
The plugin can be configured to ignore licenses for certain artifact patterns. The default is that nothing is ignored.
To override the defaults, add the licenseReport configuration closure to the build script.
apply plugin: "com.jaredsburrows.license"
licenseReport {
// Generate reports
generateCsvReport = false
generateHtmlReport = true
generateJsonReport = false
generateTextReport = false
// Copy reports - These options are ignored for Java projects
copyCsvReportToAssets = false
copyHtmlReportToAssets = true
copyJsonReportToAssets = false
copyTextReportToAssets = false
useVariantSpecificAssetDirs = false
// Ignore licenses for certain artifact patterns
ignoredPatterns = []
// Show versions in the report - default is false
showVersions = true
}The copyHtmlReportToAssets option in the above example would have no effect since the HTML report is disabled.
The useVariantSpecificAssetDirs allows the reports to be copied into the source set asset directory of the variant. For example, licensePaidProductionReleaseReport would put the reports in src/paidProductionRelease/assets. They are copied into src/main/assets by default.
The ignoredPatterns allows for ignoring artifact patterns. These can be partial or full patterns.
apply plugin: "com.jaredsburrows.license"
licenseReport {
ignoredPatterns = ["com.some.group"] // Ignores all artifacts of the given group
ignoredPatterns = ["com.some.group:some.name"] // Ignores the given artifact regardless of version
ignoredPatterns = ["com.some.group:some.name:1.2.3"] // Ignores the given artifact with the given version
