In this article, we've seen how to work with Maven profiles, so we can create different build configurations. We would begin by specifying an id for each one in our pom.xml file: Within each profile element, we can configure many elements such as dependencies, plugins, resources, finalName. After we create one or more profiles we can start using them, or in other words, activating them. Let’s say that you’re using an activeByDefault Maven profile in your build process. For more information, refer to Maven profiles. $ mvn package -P xtest, another-profile-id # multi modules, same syntax $ mvn -pl module-name package -P xtest, another-profile-id 1.4 Always add maven-help-plugin to display the active profile during the compile or package phase, it will save you a lot of debugging time. The following sample activates the first profile if you don’t select one on your own. The activeByDefault element controls whether this profile is considered active by default.. Feel free to have a look at the finished pom.xml file over on GitHub. Typically, you would set a default active profile within your project’s pom.xml file. The source code of the HelloWorldApp class looks follows:The properties file that configures Apache Log4j is called log4j.properties, and it is found from the src/main/resources directory. It has a profile in it called "dev" it looks something like this: dev true When I run "mvn clean install" in 2.0 it used this profile and all was well. A Maven profile is defined in the pom.xml, and is a feature that allows the developer to customize and configure a project build to tailor its needs. The high level overview of all the articles on the site. when you click on the checkbox it is either greyed out and checked, or just checked. This page highlights the available profiles and system properties used to affect the Maven build. Since Maven 3. According to the Maven os: ActivationOS: Specifies that this profile will be activated when matching OS attributes are detected. activation config. profile in the same POM is activated using one of the previously described true usePluginRegistry Active Maven Profiles it ssems as if the last occurance of a profile element in the pom.xml is used. And then the activeProfile property will have dev as value and then in application.properties, the line above becomes . Lastly, we can activate the profile if the property has a value other then the specified value: Another option is to enable a profile based on the JDK running on the machine. Maven should know the list of active profiles before building the model. The example application of this blog post has only one class that writes ‘Hello World!’ to a log file by using Log4j. To execute build on Windows OS, we need to explicitly tell maven to use “ winOSBuild ” profile. All profiles that are active by default are automatically deactivated when a profile in the POM is activated on the command line or through its activation config. So, for the example above, we could add plugins and their dependencies separately for integration-tests and mutation-tests. October 2, 2013 at 9:29 PM I've found the problem. We will set this profile to be active by default, by using the property unsetDefaultProfile that if not defined will activate this profile, as the true will conflict if other profiles are set, and they will be set always, either Windows or Unix profile.. So, to disable the active-on-jdk-11 profile we execute the mvn compile -P -active-on-jdk-11 command. However, if we run the Maven command and enable another profile than the activeByDefault profile is skipped. Profiles can also be set. But quickly, another way to see what is activated is to include the maven-help-plugin in our pom.xml and tie the active-profiles goal to the compile phase: Now, let's get to using them! Let’s say that you’re using an activeByDefault Maven profile in your build Project-specific profiles go into the project's, User-specific profiles go into the user's. based on some conditons (or manually using the -P parameter). IntelliJ IDEA displays the activeByDefault profile in the Maven tool window with the selected checkbox that is … First, we'll create a no-tests profile which sets the maven.test.skip property to true: Next, we'll execute the profile by running the mvn package -Pno-tests command. For instance, we can base it on a -D system property: We now activate the profile with the mvn package -Denvironment command. Using the Runc Configurations the profile with true is used. Let's say we wanted to create a profile that only ran our integration tests and another for a set of mutation tests.

Default value is: false. However, sometimes it's more convenient if they're activated automatically. Using the settings.xml is more difficult and error-prone as we have to distribute it across build environments ourselves. Actually, we already saw one way at the beginning, which is that we can activate profiles with the -P argument. So let's begin by enabling the integration-test profile: If we verify the active profiles, with the maven-help-plugin or the mvn help:active-profiles -P integration-tests command we'll get the following result: In case we want to activate multiple profiles at the same time, we use a comma-separated list of profiles: If we always want to execute a profile, we can make one active by default: Then, we can run mvn package without specifying the profiles, and we can verify that the integration-test profile is active. More than one profile can be active at a time. Focus on the new OAuth2 stack in Spring Security 5. this is the standard behaviour: This profile will automatically be active for all builds unless another It configures the JAR plugin to create an “attached” JAR with the “test” classifier.To activate this profile execute mvn -Ptest install and Maven will execute the steps in the profile in addition to the normal steps. In this tutorial, we'll learn how to work with Maven profiles. documentation This optimizes our build process and helps to give faster feedback to developers. A Build profile is a set of configuration values, which can be used to set or override default values of Maven build. Profile activation is done on very low level, almost on XML level during building the model. Our log4j.properties file looks as follows:Our Log4j configuration file looks pretty ordinary, but it has one thing that doesn’t really make any sense. To disable a profile we can use the ‘!' I installed the Java Extension Pack which includes this plugin in VSCode. Although the element in pom.xml lets you specify more than one condition, the conditions are evaluated with the OR operator rather than the AND operator.. The default is true . It's also possible to activate a profile if a property is not present: Or we can activate the profile if the property has a specific value: We can now run the profile with mvn package -Denvironment=test. All profiles that are active by default are automatically deactivated This profile targets a very specific version of Windows XP, version 5.1.2600 on a 32-bit platform. From this build you will get two artifacts, “foo-1.0.jar” and “foo-1.0-test.jar”. Also check the Active by default checkbox to enable the Maven repository. One profile may not deactivate another profile. maven-2 - not - maven profile default Activating a profile by default (2) I'm using Maven 3.0.3. When you invoke Maven from the command-line to run a plug-in goal directly, Maven uses a standalone POM that does not use the repositories listed in the settings.xml file unless they are part of a profile that is set to be "active by default". THE unique Spring Security education if you’re working with Java today. The Default Profile . この記事では、さまざまな環境（dev、test、prod）に対して異なるパラメータ（サーバまたはデータベースパラメータ）を渡すMavenのプロファイルの例をいくつか紹介します。 However, this was just an introduction to Maven profiles. Active by default Maven profile and other profiles. This plugin then chose the default profile and failed to run. Deactivating a profile. Default value is: false. For every maven command profile needs to be specified explicitly. With this change both the following commands will be equivalent {code} mvn clean install -DskipTests mvn clean install -DskipTests -Phadoop-2 {code}-- This profile will only be active for JDK versions that begin with "1.5". In this case, we want to enable the profile if the JDK version starts with 11: We can also use ranges for the JDK version as explained in Maven Version Range Syntax. Separating tests into profiles can make the default build faster by having it focus, say, on just the unit tests. 在开发过程中，我们的项目会存在不同的运行环境，比如开发环境、测试环境、生产环境，而我们的项目在不同的环境中，有的配置可能会不一样，比如数据源配置、日志文件配置、以及一些软件运行过程中的基本配置，那每次我们将软件部署到不同的环境时，都需要修改相应的配置文件，这样来回修改，很容易出错，而且浪费劳动力。 在前面的文章profile之springboot，springboot为我们提供了一种解决方案，而maven也提供了一种更加灵活的解决方案，就是profile功能。 VS Code Version: 1.38.1 Maven for Java: 0.19.1. Any bean that does not specify a profile belongs to the default profile. Once the model is built, you cannot de/activate a profile, because you will have to rebuild the model completely. when a profile in the POM is activated on the command line or through its 在maven中实现多环境的构建可移植性需要使用profile，通过不同的环境激活不同的profile来达到构建的可移植性。 一、POM中profile的配置. as if activeByDefault was set. No active profile set, falling back to default profiles: default. process. Now, we just placed these profiles in our pom.xml file, which declares them only for our project. So, let's create a test profile that only executes if the testreport.html is not yet present: We've seen many ways to activate profiles, but sometimes we need to disable one as well. Rather than specifying it from the command-line, we can set it in our maven.config file. Since you didn’t specify the active profile. jdk: String: Specifies that this profile will be activated when a matching JDK is detected. From no experience to actually building stuff​. By creating multiple properties files for the different environments or use cases, its sometimes hard to manually change the active.profile value to the right one.
