Cannot resolve java.lang.object type - Eclipse build path does not work

Question

I have a problem with Eclipse from Mac OSX Mountain Lion. I recently installed the Android SDK and in my java projects I received the following message:

The java.lang.Object type cannot be resolved. This is indirectly referenced from required .class files

Considering this problem , it would seem that I do not have the correct JRE defined in the build path of my project. Checking the project creation path using the properties> Java Build Path> Libraries. I see that there is a JRE system library next to it. However, when I click Add Library ...> JRE System Library, I get a message:

An error has occurred. See Error Log for more details. java.lang.NullPointerException

Then I try to click Eclipse> Preferences> Java> Installed JREs and see an empty list. I am trying to add ... a standard virtual machine, but I cannot find the location of my JRE./Library/Java/JavaVirtualMachines/ empty and /System/Library/Frameworks/JavaVM.framework does not exist.

Does anyone know how I can fix this problem?

Answer 1

This worked for me:

• Right click on your project -> Build Path -> Configure Build Path
• Go to the Libraries tab
• Click "Add Library" → JRE System Library → Next → Default JRE Workspace (or you can add Alternate JRE) → Done

Answer 2

Right button in the project: build path → Configure build path → Click JRE System Library → Remove

Then click: Add Library → JRE System Library → Next → Installed JREs → Select JRE → Ok → Finish → Apply

You can follow the instructions to install JDL (which includes JRE) for Mac here .

Depending on your processor, the downloaded file has one of the following names:

• jdk-8uversion-macosx-amd64.dmg
• jdk-8uversion-macosx-x64.dmg

If version is version 6 or later.

• Download the file.
• Before a file can be downloaded, you must accept the license agreement.
• From the browser download window or from the file browser, double-click the .dmg file to launch it.
  The Finder window appears containing the open field icon and the .pkg file name.

• Double-click the package icon to launch the Setup application.
