Perfect solution to the situation where eclipse cannot be opened under osx

Because downloading must be indispensable to learn java eclipse, so I downloaded it from the official website, then double-click to decompress it, and then double-click the application, and then I reported an error. What the hell? I wondered if my latest osx system would be incompatible, so I casually searched and said there was a problem with osx's own decompression software, and I needed to use the command to decompress it. tar zxvf eclipse-jee-kepler-SR2-macosx-cocoa-x86_64.tar. I don't think it's okay to try betterzip. The software after applying for betterzip will open normally. Perfect solution to the situation where eclipse cannot be opened under osx
