When I run maven install
on my multi-module Maven project I always get the following output:
[WARNING] File encoding has not been set, using platform encoding UTF-8, i.e. build is platform dependent!
So, I googled around a bit, but all I could find was that I have to add:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
...to my pom.xml file. But it's already there (in the parent pom.xml).
Configuring <encoding>
for the maven-resources-plugin or the maven-compiler-plugin also doesn't fix it.
So what's the problem?
OK, I have found the problem.
I use some reporting plugins. In the documentation of the failsafe-maven-plugin
I found, that the <encoding>
configuration - of course - uses ${project.reporting.outputEncoding}
by default.
So I added the property as a child element of the project
element and everything is fine now:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
</properties>
