Compile problem #440

Closed popkingcorn closed 4 years ago

popkingcorn commented 4 years ago

Hello, when i try to compile a project in Eclipse i get an error: [ERROR] Hint: Check that your module inherits 'com.google.gwt.core.Core' either directly or indirectly (most often by inheriting module 'com.google.gwt.user.User')

Changing GWT SDK version to 2.8.1 didn't help. It's very important for me to fix this, hope you can help...

What JRE are you using? I am using jdk1.8.0_131.

It looks like you need GWT SDK 2.8.2 to use Java 9 or later: http://www.gwtproject.org/release-notes.html#Release_Notes_2_8_2

I had JDK 13 and Java 8 Update 241 installed on my pc. In project explorer in Eclipse JRE System Library set as J2SE-1.5

I have installed jdk1.8.0_131 and it's fixed my issue! I'm very appreciate your help. Thanks a lot.

I am having the same issue with Java version "1.8.0_261".

I solved this problem by following advice on this discussion (https://stackoverflow.com/questions/11691575/how-do-upgrade-to-gwt-2-5-in-eclipse) and replaced GWT to version 2.9.0.

Here is my project setup:
