Richard Allen commented on MNG-1525:
------------------------------------
No, Runtime.getRuntime().exec("set") does not work on my OS (Red Hat Linux).
Java doesn't seem to be able to execute any of the commands that are built into
the Bash shell. What would you need to do this for anyway?
> Allow environment variables to be referenced in pom.xml, settings.xml, etc.

> Key: MNG-1525
> URL: http://jira.codehaus.org/browse/MNG-1525
> Project: Maven 2
> Type: New Feature
> Versions: 2.0
> Environment: Red Hat Linux, Java 5, Maven 2
> Reporter: Richard Allen
> Assignee: Edwin Punzalan
> Fix For: 2.0.1
>
>
> Maven should allow environment variables to be referenced; similar to Java
> System properties. Ant allows this to be done using the following syntax:
> <property environment="env"/>
> ${env.CATALINA_BASE}
> where CATALINA_BASE has been defined like:
> export CATALINA_BASE=$HOME/tomcat
> In Maven, an example use for signing jars might be:
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-jar-plugin</artifactId>
> <executions>
> <execution>
> <goals>
> <goal>sign</goal>
> </goals>
> </execution>
> </executions>
> <configuration>
> <keystore>${env.KEYSTORE_FILE}</keystore>
> <storepass>${env.KEYSTORE_PASS}</storepass>
> <alias>${env.KEYSTORE_ALIAS}</alias>
>
> <jarPath>${project.build.directory}/${project.build.finalName}.jar</jarPath>
> </configuration>
> </plugin>
> where KEYSTORE_FILE, KEYSTORE_PASS, and KEYSTORE_ALIAS are environment
> variables.
> It would also be very useful to have environment variables available when
> defining filter properties files. For instance:
> # application.properties
> deploy.dir=${env.CATALINA_BASE}/webapps
> Environment variables can be referenced in Java like:
> Map<String, String> environmentVariables = java.lang.System.getenv();
