Enabling java.autobuild.enabled causes the spring.profiles.active to be set to the default profile irrespective of the profile used for the maven build

Issue Type: Bug

1. Create a Spring.Boot application
2. Create two profiles in the pom.xml -

<profiles>
  <profile>
    <id>uat</id>
    <properties>
      <maven.test.skip>true</maven.test.skip>
      <activatedProperties>uat</activatedProperties>
    </properties>
    <build>
      <finalName>${project.artifactId}-${project.version}-uat</finalName>
    </build>
  </profile>

  <profile>
    <id>dev</id>
    <activation>
      <activeByDefault>true</activeByDefault>
    </activation>
    <properties>
      <activatedProperties>dev</activatedProperties>
      <maven.test.skip>true</maven.test.skip>
    </properties>
    <build>
      <finalName>${project.artifactId}-${project.version}-dev</finalName>
    </build>
  </profile>
</profiles>

3. Create an application.properties file for the Spring.Boot application and add the following -
   spring.profiles.active=@activatedProperties@
4. Set "java.autobuild.enabled": true in settings.json
5. Execute a maven build from within the VS Code environment -
   mvn clean package -Puat
6. Note the contents of the target application.properties file which will contain -
   spring.profiles.active=dev
7. Set "java.autobuild.enabled": false in settings.json
8. Execute a maven build from within the VS Code environment -
   mvn clean package -Puat
9. Note the contents of the target application.properties file which will contain -
   spring.profiles.active=uat

Note: If VS Code is closed and the maven command is used from a command window then the issue does not occur.

通过启用 java.autobuild.enabled、使用 Maven profiles，并比较执行 mvn clean package -Puat 后生成的 application.properties 文件，重现 settings.json 的问题。跟踪 VS Code Java 自动构建的入口点，并验证生成的 profile 仍为 uat，与在 VS Code 外部运行的构建一致。
