properties - How to filter with maven on only one property -

I want to filter with Maven on a single property with maven-war-plugin

I have properties:

• key1 = value1
• key2 = value2

  and a file: index.html

  • Hello $ {key1} - $ {key2}

    Actual results after filtering:

    • Hello price1 - value2 < Expected Result: I only want to filter property on 'key1'
      • Hello price 1 - $ {key2}

        My pom.xml:

          & lt; Plugin & gt; & Lt; Group & gt; Org.apache.maven.plugins & lt; / Group & gt; & Lt; ArtifactId & gt; Maven War Plugin & lt; / ArtifactId> & Lt; Configuration & gt; & Lt; WebResources & gt; & Lt; Resources & gt; & Lt; Filtering & gt; True & lt; / Filtering & gt; & Lt; Directory & gt; $ {Project.basedir} / src / home / webapp & lt; / Directory & gt; & Lt; / Resources & gt; & Lt; / WebResources & gt; & Lt; / Configuration & gt; & Lt; / Plugin & gt;   
         Please help me, thank you   
         
         
         from your properties file There is a clear way to remove  key2 . If this is not an option, the filtering mechanism provides an escoststring (read more about it). By default, this is a backslash.  
         In the index.html file  
          will be $ {key1} - \ $ {key2}   
         and filtering output  
          Hello value1 - $ {key2}   
         I have not really seen it with web resources, although I know this is a regular project resources works with.
