[jira] [Updated] (MNG-7318) NullPointerException during mvn install
when property is called "project.version"
[ https://issues.apache.org/jira/browse/MNG-7318?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Daniel Langerenken updated MNG-7318:
------------------------------------
Description:
Use the following pom.xml and run mvn install:
{code:java}
<?xml version="1.0" encoding="UTF-8"?><project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://maven.apache.org/POM/4.0.0" 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>org.example</groupId>
<artifactId>foo</artifactId>
<version>${revision}</version>
<name>Foo</name>
<properties>
<project.version>1.0</project.version>
<revision>${project.version}</revision>
</properties>
</project>
{code}
It will throw the following exception:
{code:java}

This is only happening when I name the property `project.version` indicating that this might be an illegal name. I can switch it to `project.ver` and it works fine.
This should not throw a NullPointerException but instead either work or throw an appropriate exception.
