Alessio Any chance you have some network connectivity issues when you attempt too build or may be a proxy that restricts certain sites? This error is indeed strange and I can’t recall having it and I’ve tried to do the same (as you describe) on my mac and all builds fine.
Also, just to compare the environments: olegs-mac:~ foo$ mvn --version Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T07:57:37-04:00) Maven home: /usr/local/Cellar/maven/3.3.3/libexec Java version: 1.8.0_112, vendor: Oracle Corporation Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home/jre Default locale: en_US, platform encoding: UTF-8 OS name: "mac os x", version: "10.11.2", arch: "x86_64", family: "mac" Cheers Oleg > On Dec 15, 2016, at 6:49 AM, Alessio Palma <[email protected]> > wrote: > > Hello all, > > I downloaded the source code from > > > http://apache.panu.it/nifi/1.1.0/nifi-1.1.0-source-release.zip > > > then unpacked the archivie and executed: > > > mvn dependency:purge-local-repository > > mvn clean install > > > and I got this: > > > [ERROR] Failed to execute goal > org.apache.maven.plugins:maven-remote-resources-plugin:1.5:process (default) > on project nifi-standard-processors: Error resolving project artifact: Could > not transfer artifact com.martiansoftware:macnificent:pom:0.2.0 from/to > org.apche.nifi (http://https://mvnrepository.com/artifact/org.apache.nifi): > https: unknown error for project com.martiansoftware:macnificent:jar:0.2.0: > Unknown host https: unknown error -> > > > > any pointers how to fix this ?
