Eclipse: Syntax Error, parameterized types are only if source level is 1.5

Question

I try to use the following code:

ArrayList
Map

Eclipse complains about both of them: Syntax Error, para

Answer 1

This works for me .

In eclipse go to project properties -> java compiler.

Then change to java higher than 1.5 .

change Compiler compliance settings to 1.6 change Generated.class files compatibility to 1.6 change Source compatibility to 1.6

Thanks.

Answer 2

My guess would be that while you run eclipse itself with JDK 1.6, it's actually configured with a different default jre.

See Window->preferences->java->Installed JREs and make sure that the checked JRE is 1.6.

If the default JRE is indeed 1.6, chances are that it's a project specific setting. See that the project is configured to use the right JRE.

Answer 3

I have experienced the same problem with Eclipse Indigo release - even though the project set up was correct. The main cause I suspect is that the workspace is defined in a separate folder from the actual source folders (as mentioned user748337). To fix the problem, I had to enable the project specific settings option (in the Porject preference) although it wasn't different from the workspace settings.

Answer 4

It can be resolved as follows:

Go to Project properties.

Then 'Java Compiler' -> Check the box ('Enable project specific settings')

Change the compiler compliance level to '5.0' & click ok

Select the checkbox for "Use default compliance settings"

Answer 5

I get this fairly regularily. Currently what's working for me (with Photon) is:

• Close project
• Open project

If this doesn't work :

• Close project
• Exit Eclipse
• Restart Eclipse
• Open Project

I know, stupid isn't it.
