+# Converting a webforJ maven project to gradle
+
+If you're working with a webforJ project and looking to switch from Maven to Gradle, this guide walks you through the key changes required to translate a typical `pom.xml` file into a working `build.gradle` script using Groovy Domain Specific Language. The examples are tailored specifically for webforJ setups, including Jetty integration, WAR packaging, and profile-based configuration.
+
+## 1. Apply required plugins
+
+webforJ typically packages the app as a WAR file and runs using Jetty. Enable the following plugins:
+
+```groovy
+plugins {
+    id 'java'
+    id 'war'
+    id 'org.gretty'
+}
+```
+
+## 2. Define project metadata
+
+These properties match the `<groupId>`, `<artifactId>`, and `<version>` entries from Maven:
+
+```groovy
+group = 'org.example'
+version = '1.0-SNAPSHOT'
+```
+
+## 3. Java version compatibility
+
+```groovy
+java {
+    toolchain {
+        languageVersion.set(JavaLanguageVersion.of(17))
+    }
+}
+```
+
+## 4. Define repositories
+
+Include Maven Central and the Sonatype snapshots repository:
+
+```groovy
+repositories {
+    mavenCentral()
+    maven {
+        url 'https://s01.oss.sonatype.org/content/repositories/snapshots'
+        mavenContent { snapshotsOnly() }
+    }
+}
+```
+
+## 5. Declare dependencies
+
+Replace the `<dependencies>` block from your `pom.xml` with:
+
+```groovy
+def webforjVersion = '25.00-SNAPSHOT'
+
+dependencies {
+    implementation "com.webforj:webforj:${webforjVersion}"
+    implementation 'org.slf4j:slf4j-simple:2.0.16'
+    testImplementation 'com.microsoft.playwright:playwright:1.49.0'
+    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.10.3'
+}
+```
+
+## 6. Resource and WAR Handling
+
+You can copy config files as part of your `processResources` phase:
+
+```groovy
+def configFile = project.hasProperty('prod') ? 'webforj-prod.conf' : 'webforj-dev.conf'
+
+tasks.register('copyWebforjConfig', Copy) {
+    from "src/main/resources/${configFile}"
+    into "$buildDir/resources/main"
+    rename { 'webforj.conf' }
+}
+
+processResources.dependsOn copyWebforjConfig
+```
+
+## 7. Gretty integration
+
+Configure your gretty setup, its going to handle the jetty deployment:
+
+```groovy
+gretty {
+    httpPort = 8080
+    contextPath = '/'
+    servletContainer = 'jetty11'
+}
+```
+
+## 8. Testing
+
+To enable JUnit 5 (Jupiter), include:
+
+```groovy
+test {
+    useJUnitPlatform()
+}
+```
+
+## 9. IDE Integration
+
+### IntelliJ IDEA
+- Open the project root folder.
+- IntelliJ will detect `build.gradle` and prompt to import.
+- Ensure the "Use Gradle from wrapper" option is enabled.
+
+### Eclipse
+- Install the Buildship Gradle plugin if not already installed.
+- Go to File → Import → Gradle → Existing Gradle Project.
+- Select your project directory and finish.
+<!-- vale off -->
+### VS Code
+<!-- vale on -->
+- Install the Java Extension Pack.
+- Open the folder, and VS Code will detect the Gradle project.
+- Use the Gradle Tasks tab or command palette to build or run tasks.
+
+
+## 10. Running the app
+
+Since you are using gretty you will need to build a gradle wrapper first. For this purpose run `gradle wrapper`.
+Now you can use `./gradlew appRun` and the task will utilize the jetty deployment automatically.
+
+The completed `build.gradle` should look similar to this:
+
+```groovy
+plugins {
+    id 'java'
+    id 'war'
+    id 'org.gretty' version '4.1.1'
+}
+
+group = 'com.gradletest'
+version = '1.0-SNAPSHOT'
+
+java {
+    toolchain {
+        languageVersion.set(JavaLanguageVersion.of(21))
+    }
+}
+
+gretty {
+    httpPort = 8080
+    contextPath = '/'
+    servletContainer = 'jetty11'
+}
+
+def webforjVersion = '25.00'
+
+repositories {
+    mavenCentral()
+    maven {
+        url 'https://s01.oss.sonatype.org/content/repositories/snapshots'
+        mavenContent { snapshotsOnly() }
+    }
+}
+
+dependencies {
+    implementation "com.webforj:webforj:$webforjVersion"
+    implementation 'org.slf4j:slf4j-simple:2.0.16'
+
+    testImplementation 'com.microsoft.playwright:playwright:1.49.0'
+    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.10.3'
+}
+
+test {
+    useJUnitPlatform()
+}
+
+def configFile = project.hasProperty('prod') ? 'webforj-prod.conf' : 'webforj-dev.conf'
+
+tasks.register('copyWebforjConfig', Copy) {
+    from "src/main/resources/${configFile}"
+    into "$buildDir/resources/main"
+    rename { 'webforj.conf' }
+}
+
+processResources.dependsOn 'copyWebforjConfig'
+
+```
