Liquibase package compilation when spec and body in same file

I have a directory where the packages are kept in the below format ,both the package specification and body are kept in the same file ,the file name is abc.pkg

create or replace package abc
 IS 
  /* this package is utility to fetch employee related data*/


 END abc;
/
create or replace package body abc
 IS 

 END abc;
/

My changeset is

<changeSet author="curious" id="PKG_1" logicalFilePath= "package/abc.pkg" runOnChange="true">
    <sqlFile path="package/abc.pkg"
            relativeToChangelogFile="true"
            endDelimiter="/"
            splitStatements="true"
            encoding="utf8"
            />
</changeSet>

The build is successful but the package got error because of / , can anyone help me with this fix , as this must be the most common way of checkin the code into version control systems like GIT and SVN
