IDEA ignores Maven Profiles

Problem:

IDEA ignores options set via Maven Profiles.

For instance, in the example below, if the Project uses JDK 8, xml-apis dependency is added to the classpath:

    <...>
      <profiles>
          <profile>
              <id>java8</id>
              <activation>
                  <jdk>1.8</jdk>
              </activation>
              <dependencies>
                  <dependency>
                      <groupId>xml-apis</groupId>
                      <artifactId>xml-apis</artifactId>
                      <version>1.4.01</version>
                  </dependency>
              </dependencies>
          </profile>
      </profiles>
    <...>

Cause:

IDEA determines the status of Maven Profiles during Maven Sync and does not re-access it when a Run Configuration starts, since it is a resource-intensive/time-consuming process.

Resolution:

• Run a Maven Sync after making the changes that affect Profiles.
• Use Maven Run Configurations.
• Enable the "Delegate build/run actions to Maven" option.
