Usage
This recipe has no required configuration options. It can be activated by adding a dependency on org.openrewrite.recipe:rewrite-quarkus
in your build file or by running a shell command (in which case no build changes are needed):
- Gradle
- Gradle init script
- Maven POM
- Maven Command Line
- Moderne CLI
- Add the following to your
build.gradle
file:
plugins {
id("org.openrewrite.rewrite") version("7.6.1")
}
rewrite {
activeRecipe("org.openrewrite.quarkus.migrate.javaee.JavaEEtoQuarkus2CodeMigration")
setExportDatatables(true)
}
repositories {
mavenCentral()
}
dependencies {
rewrite("org.openrewrite.recipe:rewrite-quarkus:2.19.0")
}
- Run
gradle rewriteRun
to run the recipe.
- Create a file named
init.gradle
in the root of your project.
initscript {
repositories {
maven { url "https://plugins.gradle.org/m2" }
}
dependencies { classpath("org.openrewrite:plugin:7.6.1") }
}
rootProject {
plugins.apply(org.openrewrite.gradle.RewritePlugin)
dependencies {
rewrite("org.openrewrite.recipe:rewrite-quarkus:2.19.0")
}
rewrite {
activeRecipe("org.openrewrite.quarkus.migrate.javaee.JavaEEtoQuarkus2CodeMigration")
setExportDatatables(true)
}
afterEvaluate {
if (repositories.isEmpty()) {
repositories {
mavenCentral()
}
}
}
}
- Run the recipe.
gradle --init-script init.gradle rewriteRun
- Add the following to your
pom.xml
file:
<project>
<build>
<plugins>
<plugin>
<groupId>org.openrewrite.maven</groupId>
<artifactId>rewrite-maven-plugin</artifactId>
<version>6.8.0</version>
<configuration>
<exportDatatables>true</exportDatatables>
<activeRecipes>
<recipe>org.openrewrite.quarkus.migrate.javaee.JavaEEtoQuarkus2CodeMigration</recipe>
</activeRecipes>
</configuration>
<dependencies>
<dependency>
<groupId>org.openrewrite.recipe</groupId>
<artifactId>rewrite-quarkus</artifactId>
<version>2.19.0</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
</project>
- Run
mvn rewrite:run
to run the recipe.
You will need to have Maven installed on your machine before you can run the following command.
mvn -U org.openrewrite.maven:rewrite-maven-plugin:run -Drewrite.recipeArtifactCoordinates=org.openrewrite.recipe:rewrite-quarkus:RELEASE -Drewrite.activeRecipes=org.openrewrite.quarkus.migrate.javaee.JavaEEtoQuarkus2CodeMigration -Drewrite.exportDatatables=true
You will need to have configured the Moderne CLI on your machine before you can run the following command.
mod run . --recipe JavaEEtoQuarkus2CodeMigration
If the recipe is not available locally, then you can install it using:
mod config recipes jar install org.openrewrite.recipe:rewrite-quarkus:2.19.0

Parent of the recipe that made changes | In a hierarchical recipe, the parent of the recipe that made a change. Empty if this is the root of a hierarchy or if the recipe is not hierarchical at all. |
Recipe that made changes | The specific recipe that made a change. |
Estimated time saving | An estimated effort that a developer to fix manually instead of using this recipe, in unit of seconds. |
Cycle | The recipe cycle in which the change was made. |
