ATG Build Plugin for gradle

This plugin allows to populate gradle dependencies for ATG modules
You could find test projects TProject and TProjectManifestGeneration in examples directory

Tested with Gradle 4.10.3, Gradle 5.4.1

Key features:

---

• Resolves dependencies by ATG modules.
• Auto discovers ATG modules in gradle project and add them as sub projects.
• Provides gradle task type which can be used to define tasks building ATG EAR artifacts.
• Prints ATG modules dependency tree.
• Supports multiple root atg modules in one gradle project.
• It is not necessary to put the project into ATG installation directory.
• Supports adding dependencies on ATG module in gradle configuration.
• Supports fetching all libs dependencies to specific folder.
• Supports ATG manifest file generation based on your build.gradle configuration.

Steps to apply plugin in your ATG project:

---

Add build script dependencies to your project

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.epam.dep.esp:atg-build-plugin:1.4'
    }
}

Define ATG folder in root project properties in build.gradle

ext.atgRoot = '/ATG-ROOT/Location'

Apply ATG plugin to all required projects

apply plugin: 'atg'

ATG modules auto-discovering

---

Allow to find atg modules and add it as sub projects automatically.
In settings.gradle:

buildscript {
    dependencies {
        classpath 'com.epam.dep.esp:atg-build-plugin:1.2'
    }
}
//Optional exclude specific modules from search
ext.excludedAtgProjects=':MyNotATGModule1, :MyNotATGModuleN'

apply plugin: 'atg'

Steps to create ear:

---

Define task:

task buildEAR(type: RunAssemblerTask) {
    modules = ['DAS']
    earName = 'DAS'
    options {
        server = 'DASServer'
    }
}

Call defined task:

gradle buildEAR

Multiple ATG root modules support

---

By default plugin uses root project name as single root atg module (placed in ATG dir)
But you can configure multiple ATG root modules in build script through property "atgRootProjects"
It receives comma separated gradle project names which will be used to detect ATG root modules

Example build.gradle:

ext.atgRootProjects=:ModuleA,:ModuleB

In this case plugin will detect two ATG root module: ModuleA and ModuleB.
Dependencies on modules must be defined as ATG-Required: ModuleA ModuleB instead of ATG-Required: TProject.ModuleA TProject.ModuleB

Since v1.2:

atgRootProjects can be defined as map in following format:

ext.atgRootProjects = :ModuleA => NewNameA, :ModuleB => NameB

In this case plugin will use map values as names of root modules.

Additional dependencies on ATG module

---

Since v1.4: added ATG-Required-If-Present support, 'atg' prefix was replaces with 'atgRequired' and 'atgRequiredIf'

Add additional dependency on any ATG module(OOTB or gradle's) to classpath for build process and for manifest generation.

Gradle configuration	Manifest ATG-Required	Manifest ATG-Required-If-Present
api	atgRequiredApi	atgRequiredIfApi
apiElements	atgRequiredApiElements	atgRequiredIfApiElements
compile	atgRequiredCompile	atgRequiredIfCompile
compileClasspath	atgRequiredCompileClasspath	atgRequiredIfCompileClasspath
compileOnly	atgRequiredCompileOnly	atgRequiredIfCompileOnly
implementation	atgRequiredImplementation	atgRequiredIfImplementation
runtimeClasspath	atgRequiredRuntimeClasspath	atgRequiredIfRuntimeClasspath
runtimeElements	atgRequiredRuntimeElements	atgRequiredIfRuntimeElements
runtimeOnly	atgRequiredRuntimeOnly	atgRequiredIfRuntimeOnly
testCompile	atgRequiredTestCompile	atgRequiredIfTestCompile
testCompileClasspath	atgRequiredTestCompileClasspath	atgRequiredIfTestCompileClasspath
testCompileOnly	atgRequiredTestCompileOnly	atgRequiredIfTestCompileOnly
testImplementation	atgRequiredTestImplementation	atgRequiredIfTestImplementation
testRuntimeClasspath	atgRequiredTestRuntimeClasspath	atgRequiredIfTestRuntimeClasspath

Example:

dependencies {
    atgRequiredCompile('DAF')
    atgRequiredCompile 'DCS'
    atgRequiredCompile 'DCS.Endeca.Base', 'DAF.Endeca.Assembler'
}

Scan ATG module manifest file

---

Plugin scan manifests files of ATG modules to read information about used libs and other ATG modules.

Use scanManifest property to disable\enable manifest scan for gradle ATG modules, by default - enabled (scan always works for OOTB ATG module).

build.gradle

project.ext.scanManifest=false

Notice: don't recommended scanManifest=true with using in your project manifest generation task.

Dependencies sink task

---

Fetch all atgClassPath dependencies jar files to dependenciesSinkPath folder.

Example:

  atg {
      dependenciesSinkPath 'build/dependencies'
  }
  dependencies {
      atgClassPath 'org.slf4j:slf4j-api:1.7.26'
      atgClassPath 'org.slf4j:slf4j-simple:1.7.26'
  }

gradle dependenciesSink

Manifest generation task

---

Manifest generation task depends on following confings for your gradle project:
atg.dependenciesSinkPath as String (default null, if not null - for each jar dependency file used its dependenciesSink task fetch path)
atg.manifestConfig as com.epam.atg.gradle.manifest.ManifestConfig

ManifestConfig field	Type	Description
manifestVersion	String	as Manifest-Version
antVersion	String	as Ant-Version
atgJ2ee	String	as ATG-J2EE
atgEarModule	String	as ATG-EAR-Module
atgProduct	String	as ATG-Product
createdBy	String	as Created-By
individualResources	Set<IndividualResource>	set of IndividualResource: Name, ATG-Client-Update-File, ATG-Assembler-Import-File
atgClientClassPath	Set<String>	as ATG-Client-Class-Path
atgClassPath	Set<String>	as ATG-Class-Path
atgRequired	Set<String>	as ATG-Required
atgRequiredIfPresent	Set<String>	as ATG-Required-If-Present
atgConfigPath	String	as ATG-Config-Path
projectClassPath	Set<String>	autofilled depends on your sourceSets, used to fill individualResources, atgClientClassPath and atgClassPath
generateAtgClientClassPath	boolean	default false, flag to fill atgClientClassPath field based on projectClassPath field
generateIndividualResources	boolean	default false, flag to fill individualResources field based on projectClassPath field
skipGeneration	boolean	default true, override to false to enable atg manifest generation task for current gradle-atg module/project
override	boolean	default false, allow generation task to regenerate manifest file, if it exists
manifestFilePath	String	default "META-INF/MANIFEST.MF"
others	Map	add custom key -> value to generated manifest file

Example: build.gradle

  atg {
      dependenciesSinkPath 'build/dependencies'
      manifestConfig {
          manifestVersion '1.0'
          atgConfigPath 'config'
          generateAtgClientClassPath true
          generateIndividualResources true
          atgProduct 'Module description'
          atgJ2ee 'j2ee-apps/web'
          atgEarModule 'j2ee-apps/eb

          skipGeneration false
          override true
          manifestFilePath 'META-INF/MANIFEST.MF'
      }
  }
  dependencies {
      atgRequiredCompile 'My.Gradle.Atg.Module', 'DCS.Endeca.Base', 'DAF.Endeca.Assembler'
      atgClassPath 'org.slf4j:slf4j-simple:1.7.26' // includes org.slf4j:slf4j-api:1.7.26
  }
gradle generateAtgManifest
