Asked 10 years, 1 month ago. Active 3 months ago. Viewed k times. Roman C Consider using Ivy and get the transitive dependency management you need, with the Ant you trust. Or bite the bullet and use the Maven directory structure.
Have you tried Ivy? No, but I've spent all of my patience with switching at this point. Maybe next time. I want to get back to coding. Can it be done with maven? Possible duplicate of How to use Maven pom to download jar files only to a specific directory? Add a comment. Active Oldest Votes. Raghuram Raghuram This is it supposed to be used for? Why do copy if it maybe already be in local repo. It is local anyway. This is not for that. If nothing is passed, then dev is considered as the default environment.
Passing the right environment can be done using -Dspring. The application JAR is loaded from lib directory. Logs are being written to logs directory. Place the assembly xml, gs-spring-boot- distribution. The gs-spring-boot-distribution. It finally creates a tar and a zip file for distribution. Build the Maven project and you will see the distributions files gs-spring-boot-distribution. Developers can run the self-contained application by performing three simple steps in any environment. Side note: All the external configuration files will be packaged in the JAR file, too.
But the configuration files in the externalized config directory are always considered by the ClassLoader as they are passed as the system parameter in the startup script, using the system parameter, -Dspring. But, you can exclude them by adding the following under the build element in pom. However, exclusion of files can be ignored. Note: The server port was set as in application.
The code can be downloaded from GitHub. Thanks for visiting DZone today,. Edit Profile. Sign Out View Profile. Over 2 million developers have joined DZone. Incorporate external dependencies for your Spring Boot app with a helping hand from Maven. But we'll see how much more we can do with just that simple POM! If you simply want to compile your test sources but not execute the tests , you can execute the following:. Now that you can compile your application sources, compile your tests, and execute the tests, you'll want to move on to the next logical step so you'll be asking Making a JAR file is straight forward enough and can be accomplished by executing the following command:.
For more information on repositories you can refer to our Introduction to Repositories but let's move on to installing our artifact! To do so execute the following command:.
Note that the surefire plugin which executes the test looks for tests contained in files with a particular naming convention. By default the tests included are:.
You have walked through the process for setting up, building, testing, packaging, and installing a typical Maven project. This is likely the vast majority of what projects will be doing with Maven and if you've noticed, everything you've been able to do up to this point has been driven by an line file, namely the project's model or POM. If you look at a typical Ant build file that provides the same functionality that we've achieved thus far you'll notice it's already twice the size of the POM and we're just getting started!
There is far more functionality available to you from Maven without requiring any additions to our POM as it currently stands. To get any more functionality out of our example Ant build file you must keep making error-prone additions. So what else can you get for free? There are a great number of Maven plugins that work out of the box with even a simple POM like we have above.
We'll mention one here specifically as it is one of the highly prized features of Maven: without any work on your part this POM has enough information to generate a web site for your project!
You will most likely want to customize your Maven site but if you're pressed for time all you need to do to provide basic information about your project is execute the following command:. This will remove the target directory with all the build data before starting so that it is fresh.
Notice the value of the version tag in the pom. During the release process, a version of x. The release process also increments the development version to x. For example, version 1. Whenever you want to customise the build for a Maven project, this is done by adding or reconfiguring plugins. For this example, we will configure the Java compiler to allow JDK 5. This is as simple as adding this to your POM:. You'll notice that all plugins in Maven look much like a dependency - and in some ways they are.
This plugin will be automatically downloaded and used - including a specific version if you request it the default is to use the latest available. The configuration element applies the given parameters to every goal from the compiler plugin.
In the above case, the compiler plugin is already used as part of the build process and this just changes the configuration.
It is also possible to add new goals to the process, and configure specific goals. For information on this, see the Introduction to the Build Lifecycle. To find out what configuration is available for a plugin, you can see the Plugins List and navigate to the plugin and goal you are using. For general information about how to configure the available parameters of a plugin, have a look at the Guide to Configuring Plugins. Another common use case that can be satisfied which requires no changes to the POM that we have above is packaging resources in the JAR file.
For this common task, Maven again relies on the Standard Directory Layout , which means by using standard Maven conventions you can package resources within JARs simply by placing those resources in a standard directory structure. If you unpacked the JAR that Maven created for you and took a look at it you would see the following:. MF as well as a pom. These come standard with generation of a JAR in Maven.
You can create your own manifest if you choose, but Maven will generate one by default if you don't. You can also modify the entries in the default manifest. We will touch on this later. The pom. One simple use might be to retrieve the version of your application. Operating on the POM file would require you to use some Maven utilities but the properties can be utilized using the standard Java API and look like the following:. At this point you would have a project directory structure that would look like the following:.
In a unit test you could use a simple snippet of code like the following to access the resource required for testing:. Sometimes a resource file will need to contain a value that can only be supplied at build time.
The property can be one of the values defined in your pom. To have Maven filter resources when copying, simply set filtering to true for the resource directory in your pom. You'll notice that we had to add the build , resources , and resource elements which weren't there before. All of this information was provided as default values previously, but because the default value for filtering is false, we had to add this to our pom.
To reference a property defined in your pom. Note that some elements of the POM have default values, so don't need to be explicitly defined in your pom. Similarly, values in the user's settings.
To continue our example, let's add a couple of properties to the application. With that in place, you can execute the following command process-resources is the build lifecycle phase where the resources are copied and filtered :. To reference a property defined in an external file, all you need to do is add a reference to this external file in your pom.
