What is very nice about this style of passing the main class instead of using a manifest is the same JAR can be used to run any main method. update the shadow plugin to a newer version to speed up the build (. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. Your email address will not be published. Earlier this year, we started implementing a new backend REST architecture for our application based on Yammer/Coda Hale’s Dropwizard Framework. Having the option (esp I’m circumstances where repos are limited) would be a massive plus. Ever run into issues where Maven/Gradle have multiple versions of the same library from different transitive dependencies? Standardmäßig erzeugt diese Task Gläser ohne Abhängigkeiten.
Ash.ta hey, thanks for the tips. Now that we have a working multi-project build lets create an executable JAR. Grundsätzlich ist ein Fat Jar (auch als Uber-Jar bekannt) ein autarkes Archiv, das sowohl Klassen als auch Abhängigkeiten enthält, die zum Ausführen einer Anwendung erforderlich sind. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. jar in order to set a java agent (say jolokia) and have it found by the JVM, there is no way to do adequate JVM options and/or classpath modification. Turning on failOnVersionConflict() will help track down and resolve all these issues. We will be using Gradle's ext tag that is used for extra properties. Fat jar should be generated upon execution of shadowJar task. This project is for StubbornJava specific undertow helper classes. Opinions expressed by DZone contributors are their own. This is a convenient location to split out our dependencies. This is also where we handle building our fat JAR using the Shadow JAR plugin. This seems to solve a problem loading static content as well. Basically, a fat jar (also known as uber-jar) is a self-sufficient archive which contains both classes and dependencies needed to run an application. Erik, I don’t think the jar task in gradle will include all the dependencies so you can’t run it standalone. Both manage dependencies well, have robust plugin systems, support checkstyles, run tests, and build/publish JARs and sources. Since 1996, we have developed an impressive history of successful enterprise software projects using the best software developers with the best tools and technologies. The root project for StubbornJava is the root on the StubbornJava GitHub repository. Learn more, ShadowJar runs extremely slow compared to fatJar. A third approach is to create a so-called "fat JAR" which is an executable JAR that includes not only your component's code, but also all of its dependencies. Jakub – 2. @Erik – we evaluated OneJar (https://github.com/rholder/gradle-one-jar) & FatJar before deciding to write Shadow. Lassen Sie uns einige wenige Änderungen an der Gradle-Aufgabe hinzufügen: Wenn Sie die ursprüngliche jar-Aufgabe unverändert lassen möchten, können Sie eine separate erstellen, die dieselbe Aufgabe erfüllt. Normally, projects only store the version numbers here, but we also store the full dependency strings so they can be reused. ./gradlew clean build shadowjar This results in two JAR files in the build/libs directory: example-fat.jar - the fat JAR without sources; example.jar - a JAR with (only) the sources; The documentation of the Gradle Shadow plug-in states that. #364 and
We only need to reference the libs. Thanks for taking a look. Thank you.
Dropwizard has a lot of transitive dependencies so that will obviously take longer. You can always update your selection by clicking Cookie Preferences at the bottom of the page. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. This could also be related to Since we also stored all of our dependency strings in a variable, we can iterate them and force their versions to always be used libs.each { k, v -> force(v) }. The build.gradle file is where we will load all plugins and include our previous gradle/dependencies.gradle file. {library name} because we stored all the dependency strings in the ext tag in the parent project. This is wonderful! Don't have one, deleted the one that got generated in 15 hours but it did look like it was similar in size as the one generated by the fatJar task. To Shadow enable your project, add the BinTray repository and the Shadow plugin dependency to your buildscript configuration like so: By default, Shadow will bundle all our your compile and runtime dependencies into an additional JAR with the classifier ‘shadow’ appended to it. Thanks for what looks to be a great plugin. https://github.com/eugenp/tutorials/tree/master/gradle
TICK – Telegraf, Influx, Chronograf, and Kapacitor – is a method of monitoring your systems and applications. Wir brauchen zwei Dinge, damit es funktioniert: ein Gradle Build Script(s) One sample snippet provided above and using following shadow task. In einfachen Projekten reicht es aus, die standardmäßige Jar-Aufgabe zu überschreiben oder eine neue zu erstellen. We only need to reference the libs. We use essential cookies to perform essential website functions, e.g. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. This file is responsible for setting the root project name and including all child projects. copy LICENSE and NOTICE into project root, chore: upgrade jvm compat to align with Gradle minimum. fat-jar was taking ~8 minutes for us to build and shadow builds in 20 or 30 seconds. Hey thanks man that helped quite a bit. Now that we have a working multi-project build, let's create an executable JAR. build.gradle This project is for StubbornJava specific common code. The build.gradle file is where we will load all plugins and include our previous gradle/dependencies.gradle file. Successfully merging a pull request may close this issue. If nothing happens, download the GitHub extension for Visual Studio and try again. The build.gradle file tends to get a bit cluttered, since dependencies are one of the most updated sections, and, self-contained, it's a great idea to split into its own file gradle/dependencies.gradle. Required fields are marked *. Multi-project builds are very useful for splitting a project into separate dependencies. #374. For more information, see our Privacy Statement. -Task verwendet werden. This project is for StubbornJava specific examples.
I got my application to work with it. In this case, any of the example servers can be run with this JAR. Any further thoughts on publishing to Maven Central? Da das Projekt jedoch wächst, wird dringend empfohlen, Plugins zu verwenden, da diese bereits schwierigere Probleme wie Konflikte mit externen META-INF-Dateien gelöst haben. It is open sourced under the ALv2 and contributions are most welcome. You should now be able to run the self contained JAR java -Denv={env} -Xmx{max-heap} -cp '{path-to-jar}' {fully-qualified-class-with-main}.
