mvncenter，maven搜索引擎

mvncenter, a more effective Maven search engine, supports direct search by class name, package name, and SHA1 value, provides an automated detection tool for JAR package versions, and detects upgradeable dependency versions in the pom.xml file with one click. The JAVA/JDK version switching visualization tool provides very simple version switching, which is a great tool for experiencing new versions of Java or developing in a multi-version JAVA environment. It is especially helpful for directly executing the command maven series of commands without relying on IDE or other pipeline tools.
