java - 由于不支持major.minor版本52.0，Eclipse无法启动

Question

有时我需要不断切换操作系统 java 版本和 eclipse java 版本(我分别通过 sudo update-alternatives --config java
和首选项 -> 选择适当的已安装 jre 来实现)。

这次，从java 8切换到java 7后，eclipse拒绝启动。当我双击该图标并选择我的工作区时，它显示:

An error has occurred. See the log file /home/user/eclipseWorkspace/.metadata/.log.

日志文件本质上是这样说的(我在最后粘贴了日志文件中的更多详细信息):

java.lang.UnsupportedClassVersionError: org/jetbrains/java/decompiler/main/decompiler/ConsoleDecompiler : Unsupported major.minor version 52.0

此问题不是类似的主要.次要版本问题的重复。我什至无法使用我的旧工作区启动 Eclipse，这是我需要的，因为有太多工作集合并了大约 150 个子项目。所以至少我需要能够提取这些工作集。如何修复此错误或导出工作集？
