How can I configure encoding in Maven?
encoding, java, maven, maven-2, maven-3
Solution
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>
See also How do I prevent "[WARNING] Using platform encoding (CP-1252 actually) to copy filtered resources, i.e. build is platform dependent!".
Problem
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?
