Eclipse Build Error #231
Description
It happened when I copied a function from another project (js) into my new ts project.
After replacing all "var" by "let" the error disappeared.
When I change a let back to var the error message starts again.

That var<=>let behavior described above was just some non-deterministic symptom I guess. The error still happened afterwards.
Changing the used typescript version from 2.4.1 to 2.3.3 did help. Now it works.
Still there is some problem with version 2.4.1.

Please try to install last version of TypeScript 2.6.2 and retry it. It's a problem with TypeScript tsserver not with typescript.java
