Does it tell you which specific one doesn't load? Sometimes networks and servers have transient problems...

It returns the unable to read repository error for all of them.

I have tried several times on different networks and its always the same

Perhaps your firewall has blocked the Eclipse application from accessing the internet?

I have been told this is not the case and the internal browser in eclipse can access them.

Could it be the version of Java?

No, it seems unlikely to be the Java version. But it is possible that if you use https URs that the Java version might not have the root certificates needed to validate the secure connection.

There's nothing in the Error Log view that might provide clues? (Or in <workspace>/.metadata/.log).

I see such warnings from low-level libraries, but still everything works.

The particular stack suggests the problem at line 103 is currently at this line:

https://git.eclipse.org/c/equinox/rt.equinox.p2.git/tree/bundles/org.eclipse.equinox.p2.artifact.repository/src/org/eclipse/equinox/internal/p2/artifact/repository/simple/SimpleArtifactRepositoryFactory.java#n106

That suggests that the content.jar was downloaded but the contents could not be processed. This all works for me and the specific file https://www.flowable.org/designer/update/content.jar does exist and looks correct to me.

It all smells to me like something a virus scanner or firewall jar scanner would cause.

You could also have a look in your <home>/.eclipse/org.eclipse.oomph.p2/cache to see what if anything has made from the internet to your machine. You can delete this cache folder to see just is freshly and recently used files. The file names in the cache folder are mangled versions of the URL from which the file came. Are empty jars showing up here? Do _p2.index files appear? Do any files beyond just those appear?

Hi Ed,

Sorry for the long down time on this.

Still trying to get this working. Looks like your correct in that its being blocked by a firewall.

Sorry i'm not a technical resource. Would be able to advise on how Eclipse is making this connection to pull down the jar file? Does it require certain ports to be open? any information would be really helpful.

It's really just using http or https protocol with whatever ports those normally use. I'm really not sure what nitty gritty technical details in that regard could really help. Have you tried temporarily just disabling your virus scanner, firewall, and defender?

Sadly I can't, i'm on the company network.

I have tried downloading the Flowable plugin and installing it manually but it still needs to contact sites for additional software (Graphiti (Incubation).

Do you know where this file can be sourced from?

Is it possible to install eclipse on a non-corporate machine, zip the eclipse files and use them on the corporate machine instead?

It is possible to create a mirror of a repository:

I had similar problems. What solved them for me was downloading new security certificates for Java. That is, I replaced the cacerts file with one from my company.

C:\Program Files\Java\jdk1.8.0_321\jre\lib\security\cacerts
