First, you noticed that part of the message you got during the install says.... The following packages have to be installed: java-1.8.0-openjdk-devel-1:1.8.0.151-1.b12.fc27.x86_64 OpenJDK Development Environment Which is telling you that maven is depending on java-1.8. Second, a question. When you ran the command did you have JAVA_HOME set? If you did, how about trying it again without it being set? -- Fedora Users List - The place to go to speculate endlessly
