TeacmCity. Custom annotations for "UnusedDeclaration" inspection

Hi.

We have a problem with our TeamCity build for run daily IDEA inspections.
Problem is with inspection "Unused Declaration" - https://youtrack.jetbrains.com/issue/IDEA-153898
This inspection shows that class unused (not instantiated) even it is marked by annotation org.springframework.stereotype.Component

As one of suggestion for this problem was - share misc.xml in VCS repo

We can't share misc.xml because of https://youtrack.jetbrains.com/issue/IDEA-153947

To fix this problem I tried to add custom build step to TC configuration - recreate misc.xml

echo "<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="EntryPointsManager">
    <entry_points version="2.0" />
    <list size="1">
      <item index="1" class="java.lang.String" itemvalue="org.springframework.stereotype.Component" />
    </list>
  </component>
</project>" > .idea/misc.xml

But looks like it doesn't help

My questions:
1. Can be there any problems with such custom build step with modifying file in .idea folder? I asked because of this - https://youtrack.jetbrains.com/issue/TW-42095
2. Is there any way to make sure that TeamCity IDEA inspection loaded mics.xml?
It's not clear from logs:
