Maven error with maven-clean-plugin

Question

I'm new to maven and i'm trying to use the following command :

mvn clean install -DskipTests=true

but i get the following error :

[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:3.0.0 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-clean-plugin:jar:3.0.0: Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom:3.0.0 from/to central (https://repo.maven.apache.org/maven2): java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty -> [Help 1]

I have absolutly no idea of what i'm missing. Here is my pom.xml
