Maven build fails to filter app.properties due to wrong encoding

[xxxyyyz]

Building the freshly cloned project with mvn package leads to the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.3.1:resources (default-resources) on project validationtool: filtering /Users/jlink/dev/projects/kosit-validator/src/main/resources/app-info.properties to /Users/jlink/dev/projects/kosit-validator/target/classes/app-info.properties failed with MalformedInputException: Input length = 1 -> [Help 1]

Seems like the filter step of files in src/main/resources fails due to wrong encoding (property files are required to be in ISO-8859-1 by JLS), but the pom.xml defines the source encoding to be UTF-8.

According to the maven-resource-plugin documentation [1], the following configuration in pom.xml resolves the issue:

             <plugin>
                 <groupId>org.apache.maven.plugins</groupId>
                 <artifactId>maven-resources-plugin</artifactId>
                 <version>3.3.1</version>
                 <configuration>
                   <propertiesEncoding>ISO-8859-1</propertiesEncoding>
                 </configuration>
             </plugin>

This is also a duplicate of #146. Was fixed in 1.5.2. Thank you for pointing it out
