Migrate to Java 11
org.openrewrite.java.migrate.Java8toJava11
This recipe will apply changes commonly needed when upgrading to Java 11. Specifically, for those applications that are built on Java 8, this recipe will update and add dependencies on J2EE libraries that are no longer directly bundled with the JDK. This recipe will also replace deprecated API with equivalents when there is a clear migration strategy. Build files will also be updated to use Java 11 as the target/source and plugins will be also be upgraded to versions that are compatible with Java 11.

Usage
This recipe has no required configuration options. It can be activated by adding a dependency on org.openrewrite.recipe:rewrite-migrate-java:2.26.1
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("6.25.0")
}
rewrite {
activeRecipe("org.openrewrite.java.migrate.Java8toJava11")
exportDatatables = true
}
repositories {
mavenCentral()
}
dependencies {
rewrite("org.openrewrite.recipe:rewrite-migrate-java:2.26.1")
}
- 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:6.25.0") }
}
rootProject {
plugins.apply(org.openrewrite.gradle.RewritePlugin)
dependencies {
rewrite("org.openrewrite.recipe:rewrite-migrate-java:2.26.1")
}
rewrite {
activeRecipe("org.openrewrite.java.migrate.Java8toJava11")
exportDatatables = 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>5.42.0</version>
<configuration>
<exportDatatables>true</exportDatatables>
<activeRecipes>
<recipe>org.openrewrite.java.migrate.Java8toJava11</recipe>
</activeRecipes>
</configuration>
<dependencies>

<artifactId>rewrite-migrate-java</artifactId>
<version>2.26.1</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-migrate-java:RELEASE -Drewrite.activeRecipes=org.openrewrite.java.migrate.Java8toJava11 -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 Java8toJava11

Cycle | The recipe cycle in which the change was made. |
Source files that errored on a recipe
org.openrewrite.table.SourcesFileErrors
The details of all errors produced by a recipe run.
Column Name | Description |
---|---|
