Upgrading plugin from 1.6 to 1.7

Question

I am trying to upgrade a project (a set of plugins) from 1.6 to 1.7. So I changed in MANIFEST.MF from Bundle-RequiredExecutionEnvironment: JavaSE-1.6 to Bundle-RequiredExecutionEnvironment: JavaSE-1.7 However, after that upgrade, if I try to export the plugin as a plugin fragment, I got this Eclipse error:

Processing inclusion from feature org.eclipse.pde.container.feature: Bundle myplugin_1.0.0 failed to resolve.:
    Missing Constraint: Bundle-RequiredExecutionEnvironment: JavaSE-1.7
    Host plug-in JavaSE_0.0.0 has not been found.

Edit:

MANIFEST.MF:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Auth Plug-in
Bundle-SymbolicName: __NAME__;singleton:=true
Bundle-Version: 1.0.0
Bundle-Vendor: AVendor
Bundle-RequiredExecutionEnvironment: JavaSE-1.7
Export-Package: __A_PACKAGE_NAME__

If I change the Target-Platform to Running platform , the error disappears (but oviously, I cannot switch the target platform for the whole project). So I suspect the target platform is wrong in some way...

EDIT:

If I remove the line

Bundle-RequiredExecutionEnvironment: JavaSE-1.7

the export is successful.

Answer 1

Uh, the project used eclipse 3.5.1, which should be run on 1.6, not on 1.7. My bad.

Answer 2

As noted above:

I had the same problem with an RCP application which I upgraded to Java 8. Removing the 'Bundle-RequiredExecutionEnvironment' entry from the bundle manifest helped.

Answer 3

I had a similar problem using Eclipse Mars 4.5.0 (Build id: 20150621-1200) and Java 8.

MANIFEST.MF

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
...
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
Import-Package: org.osgi.framework;version="1.3.0"

I did not remove the line "Bundle-RequiredExecutionEnvironment: JavaSE-1.8", i changed it to "Bundle-RequiredExecutionEnvironment: JavaSE-1.7" and everything works fine.
