Maven profiles are a feature in Apache Maven that allow you to customize the build process based on different environments or conditions. Profiles can be used to define different sets of configurations, dependencies, and build steps for specific scenarios.
For example, you can have a profile for development, testing, or production environments, each with its own specific configuration. By activating a profile, you can ensure that the corresponding settings are applied during the build.
To define a profile in Maven, you need to add a `<profile>` element in the project's pom.xml file. Within the profile, you can specify various elements such as `<id>`, `<activation>`, and `<properties>` to define the profile's characteristics and conditions for activation.
Here is an example of a Maven profile that activates based on a specific property:
```xml
<profiles>
<profile>
<id>development</id>
<activation>
<property>
<name>env</name>
<value>dev</value>
</property>
</activation>
<properties>
<api.url>http://dev.api.example.com</api.url>
</properties>
</profile>
</profiles>
```
In this example, the "development" profile will be activated when the `env` property is set to "dev". It also sets the `api.url` property to the development environment's API URL.
To build a project with a specific profile, you can use the `-P` option followed by the profile ID:
```
mvn clean install -P development
```
This command will activate the "development" profile during the build.
