Embedding DTD entities in POM files
Hello,
I am trying to embed DTD Entities in the POM files. Is this supported? If
not, is there a plan to support this in 2.1 or future release?
Here is my simple example-
--- POM.XML ---
<?xml version="1.0"?>
<!DOCTYPE project [
<!ENTITY SheBang SYSTEM 'file:MYDTD.XML'>
]>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany.app</groupId>
<artifactId>my-app</artifactId>
<packaging>jar</packaging>
<version>1.0-SNAPSHOT</version>
&SheBang;
</project>
--- END (POM.XML) ---
--- MYDTD.XML ---
<name>my-app</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
--- END (MYDTD.XML) ---
When I run mvn clean install, I get exception-

Re: Embedding DTD entities in POM files
Posted by Wayne Fay <wa...@gmail.com>.
No, this is not currently supported, nor is support likely in the future.
But there have been discussions on dev@ about adding "pom mixins"
which would give you more or less the same functionality. Search the
archives for "mixin" -- you're bound to find it.
