I appear to be unable to install any signed packages from the Eclipse Marketplace. I have tried several plugins but the one I am after is Jaspersoft Studio 6.3.1. When I select it in the “Install from Catalog…” menu I am asked to confirm that the features “Jaspersoft Studio 6.3.1” and “com.jaspersoft.studio.feature” to be included in the provisioning operation. When I confirm I get the a “Proceed With Installation?” box telling me “The following solutions are not available: Jaspersoft Studio 6.3.1.” and asking me whether to proceed anyway, which I declined.

I’ve attached a few screen grabs that show the errors and will paste the event details for the error below.

I’ve tried this on two different machines with the same result. Both share some firewall configuration parameters set by my company’s IT group so it could be some sort of network/proxy issue but my research so far suggests an omission in the MyEclipse 2016/binary/com.sun.java.jdk8.win32.x86_64_1.8.0.u66/jre/lib/security/cacert file that installs with MyEclipse.

Event detail for error:

BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US

Lee,

Sorry that you are seeing this issue. Thank you for the screenshots.
I could replicate the issue at my end. I have raised a bug for the dev team to investigate further.

I could install Jaspersoft Studio 6.3.1 successfully when I started MyEclipse with a different JDK. Edit the myeclipse.ini file located in the MyEclipse install folder and add the -vm arg pointing to an external jdk as shown below :

-vm
C:/Program Files/Java/jre1.8.0_111/bin/javaw.exe

Please give it a try. We will keep you posted about the fix with the MyEclipse JDK.

Apologies for inconvenience caused. Please let us know how it works for you.
