Invalid project description

When I open the first class in my SAP Hybris workspace the language server starts up and then after some time outputs the following log:

It would be nice to know which project it is and what caused this

Environment

• Operating System: macOS 10.12.6 (16G1314)

• Visual Studio Code version: 1.24.1 (1.24.1)
• Java extension version: 0.27.0

Steps To Reproduce

See above

[attach a sample project reproducing the error] -> that's exactly the problem!!
attach logs

Current Result

Only stacktrace is printed to the console

Expected Result

Output more infos, so that the issue can be fixed.

从 EclipseProjectImporter.java 中的 EclipseProjectImporter.importDir 开始，堆栈跟踪显示项目创建失败，并跟踪正在导入的目录。使用报告中的 SAP Hybris 工作区重现问题，并改进诊断输出，使其能够识别项目以及描述无效的原因。
