Description

I am trying to filter my log4j.properties file in WEB-INF. One line is troublesome. The resulting line should be

log4j.appender.mine.File=$

{myProject.root}

/WEB-INF/logs/mine.log

where myProject is the value of the property project.artifactId.

I try

log4j.appender.mine.File=${$

{project.artifactId}

.root}/WEB-INF/logs/mine.log

but no substitution is done.

After much trial and error, I use

log4j.appender.mine.File=!#!$$

{log4j.root}

/WEB-INF/logs/mine.log

and the following in my pom.xml

<properties>
<log4j.root>{$project.artifactId}.root}</log4j.root>
</properties>
...
<build>
<plugins>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.1-beta-1</version>
<configuration>
<escapeString>!#!</escapeString>
...
</configuration>
</plugin>
</plugins>
</build>
...

this most probably is a maven filtering bug and not a maven war bug. Your description is not very clear: are you saying that you found out a solution to the issue but it's overcomplicated?

Yes. There is a solution. It is overcomplicated and not intuitive.

I am having the same problem. An attempt to configure this:

export SERVER_ENV=\${SERVER_ENV:${httpd.server.env}}

results in this:

export SERVER_ENV=${SERVER_ENV:${httpd.server.env}}

instead of this:

export SERVER_ENV=${SERVER_ENV:sandbox}
