在Eclipse中导入解决错误

Question

for a little project of mine I want to read a JSON from a Webservice. For this I want to use GSON. My Problem is that I cannot import the dependencies into my eclipse-project. I put the jars into my classpath and they really are in the .classpath-File. The strange thing is, that the eclipse autocomplete suggests me to import the GSON-FIles, but in the import section the import "com.google" cannot be resolved.

It looks like this: Picture of file in eclipse

It also does not only happen with GSON, it seems like nothing from a imported .jar can be resolved.

I hope one of you guys knows a solution to my problem.

EDIT

I figured it out myself, didn't consider the module-info java10 creates. By adding requires gson it worked fine.

Answer 1

Right click on your project> Properties> java build path> Libraries are you able to see the required jar file if not please add via add external jars. Do Project > clean

Answer 2

1. Remove existing jar entry from build path.
2. Put the jar gson-2.2.4.jar in some folder, for example E:\\external-jar\\gson-2.2.4.jar
3. Right click on the project and go to build path then click on "Add External Archives..".
4. Select the gson-2.2.4.jar and click open.
5. The gson-2.2.4.jar will now appear in the referenced libraries.

Hope this help! Let me know if you still face issues.
