Java Eclipse无法启动，因为不支持major.minor版本52.0

有时我需要不断切换我的OS java版本和eclipse java版本，这是通过sudo update alternations-config java实现的 和首选项->分别选择合适的已安装jre

这次，在从Java8切换到Java7之后，eclipse拒绝启动。当我双击图标并选择我的工作区时，它会显示：

发生了一个错误。查看日志文件 /home/user/eclipseWorkspace/.metadata/.log

日志文件本质上是这样说的：我在末尾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

此问题与类似的主要版本和次要版本问题不同。我甚至不能用我的旧工作区启动eclipse，我需要这样做，因为有太多的工作集整合了大约150个子项目。因此，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

这次，在从Java8切换到Java7之后，eclipse拒绝启动

---

现代Eclipse要求它使用Java8运行。

您似乎正在使用Jetbrains反编译器代码运行EclipseMars4.5。EclipseMars将使用Java7运行，但Jetbrains代码需要Java8或更高版本

我不得不使用一个新的空工作区来启动eclipse，卸载eclipse类反编译器3.1.1，然后用我的旧工作区重新启动eclipse，它成功了。谢谢你指出这一点。干杯
