问题 I have a Maven project with multiple modules and sub-modules and i want to compile it at once, i.e. using only one call to "mvn clean install". For a basic project, the following structure would work: . ├── modules │ ├── moduleA │ │ └── pom.xml <--- Module A POM │ ├── moduleB │ │ └── pom.xml <--- Module B POM │ └── pom.xml <--- Super POM (at the root of "modules" folder) └── pom.xml <--- Aggregator POM With the aggregator being: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi=

问题 I have a multi-module Maven project. For the sake of this example, consider two modules: data consumer Module consumer has module data as a dependency. Module data declares a bunch of core classes. There are tests under src/test that use them. These tests require some long-winded object creation, so I have a class with some utility methods in it to create these objects. This utility class ( SampleDataHelper ) is in the src/test hierarchy. I also have some tests in the consumer module that

问题 I have a profile in my pom.xml which should be always active unless it is explicitely deactivated (-P !firstProfile). I solved this by using the activeByDefault flag: <profiles> <profile> <id>firstProfile</id> <activation> <activeByDefault>true</activeByDefault> </activation> ... </profile> </profiles> Now in the same pom.xml I have a second profile defined this should only be active if the profile is really activated (-P secondProfile). So the default behaviour is: firstProfile active,

问题 I'm new to Intellij Idea, i just import a project with pom.xml , but the ide didn't resolve anything in maven dependencies. Anything defined in pom.xml dependencies when import in code raise an error cannot resolve symbol xxxxx But mvn install will work, i try import the dependencies in Project Settings/Libraries in .jar files, then it works, but could the ide resolve libraries defined in pom.xml ? i don't want to do that everytime.

问题 In a Maven project, I have test classes and source classes in the same package, but in different physical locations. .../src/main/java/package/** <-- application code .../src/test/java/package/** <-- test code It's no problem to access the source classes in the test classes, but I would like to run a test runner in the main method and access the AllTest.class so that I can create jar and execute my tests. public static void main(String[] args) { // AllTest not found Result result = JUnitCore

问题 What is the difference between mvn clean install and mvn install ? 回答1: clean is its own build lifecycle phase (which can be thought of as an action or task) in Maven. mvn clean install tells Maven to do the clean phase in each module before running the install phase for each module. What this does is clear any compiled files you have, making sure that you're really compiling each module from scratch. 回答2: Maven lets you specify either goals or lifecycle phases on the command line (or both).
