How to build uberJar with Quarkus-Gradle-Plugin

Question

I'm trying to build an uberJar with all the dependencies (runnable) using the Quarkus Gradle plugin. With maven you can build it by adding a config to the plugin.

That's what it looks like in maven:

<plugin>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-maven-plugin</artifactId>
    <version>${quarkus.version}</version>
    <configuration>
        <uberJar>true</uberJar>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>build</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Is there any possibility to set this property in the gradle plugin? id 'io.quarkus.gradle.plugin' version '0.12.0'

Answer 1

The name of that option is "uber-jar". To set this property you have to start the build like that from command line:

>gradle quarkusBuild --uber-jar

I had some bugs during the build, like that one

Caused by: java.nio.file.NoSuchFileException: /Users/sven/Idea/getting-started/build/getting-started.jar

but in the end the build was successful

Answer 2

quarkusBuild任务包含一个名为uberJar的属性，您可以使用它来控制 uberJar 行为（请参阅此）。

Answer 3

You can directly configure the task in your build.gradle using something like:

task buildUberJar(type: io.quarkus.gradle.tasks.QuarkusBuild, dependsOn: build) {
    uberJar = true
}

However, I see a lot of issues with overlapping resources between the jars with this approach. Here is a subset of my output:
