The CycloneDX Gradle plugin creates an aggregate of all direct and transitive dependencies of a project and creates a valid CycloneDX SBOM. CycloneDX is a lightweight software bill of materials (SBOM) specification designed for use in application security contexts and supply chain component analysis.
Execution:
gradle cyclonedxBomOutput CycloneDX Generation Info:
gradle cyclonedxBom -infobuild.gradle (excerpt)
To generate BOM for a single project add the plugin to the build.gradle.
plugins {
id 'org.cyclonedx.bom' version '1.8.2'
}Once a BOM is generated, by default it will reside at ./build/reports/bom.xml and ./build/reports/bom.json
Configuration:
You can add the following configuration to build.gradle to control various options in generating a BOM:
cyclonedxBom {
// includeConfigs is the list of configuration names to include when generating the BOM (leave empty to include every configuration), regex is supported
includeConfigs = ["runtimeClasspath"]
// skipConfigs is a list of configuration names to exclude when generating the BOM, regex is supported
skipConfigs = ["compileClasspath", "testCompileClasspath"]
// skipProjects is a list of project names to exclude when generating the BOM
skipProjects = [rootProject.name, "yourTestSubProject"]
// Specified the type of project being built. Defaults to 'library'
projectType = "application"
// Specified the version of the CycloneDX specification to use. Defaults to '1.5'
schemaVersion = "1.5"
// Boms destination directory. Defaults to 'build/reports'
destination = file("build/reports")
// The file name for the generated BOMs (before the file format suffix). Defaults to 'bom'
outputName = "bom"
// The file format generated, can be xml, json or all for generating both. Defaults to 'all'
outputFormat = "json"
// Exclude BOM Serial Number. Defaults to 'true'
includeBomSerialNumber = false
// Exclude License Text. Defaults to 'true'
includeLicenseText = false
// Override component version. Defaults to the project version
componentVersion = "2.0.0"
}If you are using the Kotlin DSL, the plugin can be configured as following:
tasks.cyclonedxBom {
setIncludeConfigs(listOf("runtimeClasspath"))
setSkipConfigs(listOf("compileClasspath", "testCompileClasspath"))
setSkipProjects(listOf(rootProject.name, "yourTestSubProject"))
setProjectType("application")
setSchemaVersion("1.5")
setDestination(project.file("build/reports"))
setOutputName("bom")
setOutputFormat("json")
setIncludeBomSerialNumber(false)
setIncludeLicenseText(true)
setComponentVersion("2.0.0")
}Run Gradle with info logging (-i option) to see which configurations add to the BOM.
Generate BOM for multiple projects:
You can also build the BOM for multiple projects using the --init-script option:
gradle --init-script <path-to-init.gradle> cyclonedxBom -infowhere the init.gradle can look like this:
initscript {
repositories {
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath "org.cyclonedx:cyclonedx-gradle-plugin:1.8.2"
}
}
allprojects{
apply plugin:org.cyclonedx.gradle.CycloneDxPlugin
cyclonedxBom {
includeConfigs = ["runtimeClasspath"]
skipConfigs = ["compileClasspath", "testCompileClasspath"]
skipProjects = [rootProject.name, "yourTestSubProject"]
projectType = "application"
schemaVersion = "1.5"
destination = file("build/reports")
outputName = "bom"
outputFormat = "json"
includeBomSerialNumber = false
includeLicenseText = true
componentVersion = "2.0.0"
}
}The Plugin makes it possible to manually add Manufacture-Data and Licenses-Data to the Metadata of the BOM.
The structure of the Metadata is shown on https://cyclonedx.org/docs/1.5/json/#metadata.
The editing of the Manufacture and Licenses-Data is optional. If the Manufacture/Licenses-Date isn't edited,
then the respective structure won't appear in the BOM.
To enable the modification of the metadata the cyclonedx-core-java plugin must be implemented in the build.gradle.
In order to be able to define the Manufacture-Data you must import org.cyclonedx.model.*; into the build.gradle.
You can add the Manufacture-Data by passing an Object of the Type OrganizationalEntity to the Plugin.
Example (groovy):
cyclonedxBom {
//declaration of the Object from OrganizationalContact
OrganizationalContact organizationalContact = new OrganizationalContact()
//setting the Name[String], Email[String] and Phone[String] of the Object
organizationalContact.setName("Max_Mustermann")
organizationalContact.setEmail("[email protected]")
organizationalContact.setPhone("0000 99999999")
//passing Data to the plugin
organizationalEntity {oe->
oe.name = 'Test'
oe.url = ['www.test1.com', 'www.test2.com']
oe.addContact(organizationalContact)
}
}Example (Kotlin):
cyclonedxBom {
//declaration of the Object from OrganizationalContact
var organizationalContact1 = OrganizationalContact()
//setting the Name[String], Email[String] and Phone[String] of the Object
organizationalContact1.setName("Max_Mustermann")
organizationalContact1.setEmail("[email protected]")
organizationalContact1.setPhone("0000 99999999")
//passing Data to the plugin
setOrganizationalEntity{oe->
oe.name = "Test";
oe.urls = listOf("www.test1.com", "www.test2.com")
oe.addContact(organizationalContact1)
}
}It should be noted that some Data like OrganizationalContact, Url, Name,... can be left out.
OrganizationalEntity can also include multiple OrganizationalContact.
For details look at https://cyclonedx.org/docs/1.5/json/#metadata.
In order to be able to define the Manufacture-Data you must import org.cyclonedx.model.*; into the build.gradle.
You can add the Licenses-Data by passing an Object of the Type LicenseChoice to the Plugin. The Object from LicenseChoice includes either License or Expression. It can't include both.
Example (groovy):
cyclonedxBom {
//declaration of the Object from AttachmentText -> Needed for the setting of LicenseText
AttachmentText attachmentText = new AttachmentText()
attachmentText.setText("This is a Licenses-Test")
//declaration of the Object from License
License license = new License()
//setting the Name[String], LicenseText[AttachmentText] and Url[String]
license.setName("XXXX XXXX Software")
//license.setId("Mup") // either id or name -> both not possible
license.setLicenseText(attachmentText);
license.setUrl("https://www.test-Url.org/")
//passing Data to Plugin
licenseChoice {lc->
lc.addLicense(license)
}
}Example (Kotlin):
cyclonedxBom {
//declaration of the Object from AttachmentText -> Needed for the setting of LicenseText
val attachmentText = AttachmentText()
attachmentText.setText("This is a Licenses-Test")
//declaration of the Object from License
val license = License()
//setting the Name[String], LicenseText[AttachmentText] and Url[String]
license.setName("XXXX XXXX Software")
//license.setId("Mup") // either id or name -> both not possible
license.setLicenseText(attachmentText)
license.setUrl("https://www.test-Url.org/")
//passing Data to Plugin
setLicenseChoice{lc->
lc.addLicense(license)
}
}It should be noted that License requires either Id or Name, but both can't be included at the same time.
Text and Url are optional for inclusion and multiple License can be added to LicenseChoice.
Example (groovy):
cyclonedxBom {
//passing Expression to Plugin
licenseChoice {lc->
lc.setExpression("This is a Test Expression")
}
}Example (Kotlin):
cyclonedxBom {
//passing Expression to Plugin
setLicenseChoice{lc->
lc.setExpression("This is a Test Expression")
}
}For details of the BOM structure look at https://cyclonedx.org/docs/1.5/json/#metadata.
