Unbound JavsSE 1.7 libraries in the Java Eclipse Project

Question

I am very new to Java and Eclipse. I am working on a java project that uses Jave SE 1.7. I had a version of Java 1.6 installed on Mac OS. I installed Jave SE 1.7 now to run this project, but JavaSE 1.7 (unbound) displayed in the project libraries section. The project does not compile and does not show many errors. How to link JavaSE 1.7 library to a project?

Answer 1

After installing jdk 7 you need to report this to Eclipse. Window -> Preferences -> Java -> Installed JREs.
After that, tell your project which the JRE will use if the new one is not standard.

Answer 2

Check out these two panels. Remove unlimited 1.6 JREs and then configure the newly installed 1.7 JRE.

Answer 3

To add to the above answers, you must also confirm that the project uses the Java 1.7 compiler level. Right-click in the project and click Properties . Click Java Comiler and verify that Java 1.7 is also installed at the compiler level. See image below.

Answer 4

Hi, I had this problem too, but for me the 1.8 JRE was unrelated. The process for resolving this issue remains the same.

• Go to Eclipse -> Settings
• Java → Installed JRE
• You will see Java SE 6 already and checked.
• To see the other JREs that you have installed, click the Search button.

5. Now you will see the other JREs that you installed, now mark the JRE you want to use and restart Eclipse.

Answer 5

For Eclipse on Windows:

Select Windows-> Preferences-> Java-> Installed JREs-> Add.

Select the type of JRE and click Next.

Select "Directory ..." and find the jre7 folder, usually located under C: \ Program Files \ Java \ jre , click "Finish".

After adding, select jre7 and click OK.
