Solve the problem that the source code of the jar package opened by eclipse in ubuntu environment is garbled. In ubuntu environment, the jar package developed in windows environment is referenced in eclipse. When the source code is opened, all Chinese comments become garbled, this is because the jar package is encoded as GBK during development, which is not supported by Ubuntu by default. How can we solve this problem? You can perform the following two steps: 1. Modify/var/lib/locales/supported. d/local file, add zh_CN.GBK GBK zh_CN.GB2312 GB2312 www.2cto.com to the file, and then execute the sudo dpkg-reconfigure -- force locales command. In the execution result, if zh_CN.GB2312 donezh_CN.GBK done is displayed, GBK encoding is supported. 2. In the Windows -- Preferences -- Generan -- Workspace menu of eclipse, set the Text file encoding item to GBK and restart eclipse.
