TaskList Many Plugins in META-INF/services/

Out team have created camunda application using spring boot. There was written one plugin for TaskList inside the same project (not the separate jar. file).
Now we have to add another plugin for task list. Is it possible to add another entry in file org.camunda.bpm.tasklist.plugin.spi.TasklistPlugin?

The file will look like this:
eu.sym.process.plugin.HistoryPlugin
eu.sym.process.plugin.ComplaintsHistory

Problem was in different place in project.
File should contains plugin in this format (as described above is correct):

eu.sym.process.plugin.HistoryPlugin
eu.sym.process.plugin.ComplaintsHistory
