[Eclipse] Access restriction: Class is not accessible due to restriction on required library @Digizol

"Access restriction: Class is not accessible due to restriction on required library"; error message may be shown while developing Java projects in Eclipse IDE. Error message is self-explanatory, some classes can not be loaded into the project since restriction rules are being imposed on those classes.

How to solve

This error message can be removed by changing a setting inside Eclipse IDE. Open up the dialog box shown below, using any of the following paths.

Windows -> Preferences -> Java -> Compiler -> Errors/Warnings
(Project) Properties -> Java Compiler -> Errors/Warnings

Locate the "Forbidden reference (access rules)" option under "Deprecated and restricted API" section in the dialog box. This option decides how to handle access rules defined inside Eclipse. By default it is set to "Error" which causes Eclipse to complain about references to any restricted classes. Choosing any other option (Warning or Ignore) will remove these error messages.

"Warning" or "Ignore" options will only hide the potential issue in the project, by allowing the project to use any classes ignoring predefined access rules. To completely resolve this issue, analyze the project and located the use of restricted classes and take necessary actions (either remove those references or access rules).

This post does not appear to provide a satisfactory solution to the problem, but merely explains how to make the warning go away. If you see the error "Access restriction: The method (name) from the type (class) is not accessible due to restriction on required project (project)" can be solved by 1) Right click on the project with the problem and select "properties"; 2) Select "Java Build Path"; 3) Expand "Plug-in Dependencies" and expand the project causing the problem; 4) Expand "Access rules" and modify them to ensure the referenced class is accessible.

The post by Anonymous on March 27, 2009 1:59AM does not solve the problem either. By modifying the Access Rules you are simply hiding the problem. The Access Rules are there for a reason and you need to fix the problem. If you don't, you are probably in violation of the Java license.

A BIG problem, with a SIMPLE solution.

Thanks a lot.
Mick on June 18, 2009 4:13 PM

I encountered this when creating a maven apache cxf prototype. The problem was not fixable by changing access rules for the library because these were not modifiable. The solution for me was to use a newer JDK or change the Order/Export (I think this is class loader order) so the Maven-supplied jaxb-api2.1.jar was used. The workspace Java 1.5 system library was not correctly exporting the javax.jws.* package. My approach was just to change the system library to a 1.6 one.

The Anonymous of March 27, 2009 1:59 AM was right. The other way to do the same things is to use plugin editor and add there on Runtime page the project/package you want to get from the class with error. This will allow the package to export. But this solution makes sense only for those who works with several projects of their own (like in case of plug-ins development). In simple cases when the error doesn't say anything to you the suggested by Kamal way is possibly one you are looking for. And then don't mess with the restriction editing.

My problem is "Access restriction to all class in /usr/java/zenith_jdk1.6.0_04/jre/lib/rt.jar".
The solution for me was to change the (Project) Properties -> Order/Export (I think this is class loader order), I just moved the "JRE System Library [zenith_jdk1.6.0_04]" above others.

"My problem was solved when I put the JDK at the end of the "Order and Export".
Totally, its really strange why eclipse fails to load classes that are below the JRE.
Anonymous on December 22, 2009 9:57 AM

Here another fix this issue:
I get the "Access restriction: The type xxxxx is not accessible due to restriction on required project.." compilation error ¶

* If you just created a new service interface, then you probably forgot to add it in the "Exported Packages" of the .services project.
* If you encounter rt.jar Restrictions (on com.sun... classes for example) - these seem to be built-in Restrictions of Eclipse 3.3/OSGi and indicate you are doing something deprecated in OSGi. Try to do it "the right way".

Aniruddha on February 15, 2010 12:54 PM

Thanks Mike for the direction.

This is how I did in Eclipse 3.5:
Right Click on Project and select Properties -> Java Build Path -> Libraries (Tab)

expand the rt.jar and see where you have forbidden access (**/*) in my case.

Now edit "access rules" -> Add -> Resolution = "Accessible" and Rule Pattern = **/*

Click OK and you are done.
