Answer 1

错误日志表明jar文件似乎已损坏。

java.util.zip.ZipException: invalid LOC header (bad signature)

在Mac中：

尝试在月食中访问About Eclipse > Installation Details > Installation History并恢复到稳定的上一个配置。完成后，重新启动eclipse，然后再次尝试安装。

根据我的个人经验，安装Eclipse有时会很困难。

因此，更好的方法是下载一个方便的eclipse便携式版本，您也可以重复使用它。

1. 转到此：https://www.eclipse.org/downloads/packages/release/2019-09/r（注意：您也可以选择其他版本的eclipse）。

1. 单击特定版本进行下载。例如：对于Windows，您将下载zip。

1. 解压缩zip并启动eclipse.exe。您不需要安装。
