Hello,

 

I'm having issues getting the plugin to install. I'm receiving the following error:
```

Unable to read repository at https://public.dhe.ibm.com/ibmdl/export/pub/software/websphere/wasdev/u….
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

```

The Eclipse version I have to use is:
```

Eclipse IDE for Enterprise Java Developers (includes Incubating components)

Version: 2020-06 (4.16.0)
Build id: 20200615-1200

```

I haven't found any assistance while looking into the issue. Is there a workaround for this problem?

 

Thanks,

Adam

Hi Adam,

I think this is an issue with your Java's security not recognizing the root certificate authority (CA) SSL certificate of https://public.dhe.ibm.com

Have a look at these Stack Overflow issues and see if they can help you install the certificates locally.

This plugin breaks Maven integration as soon as you install it in any of the latetest versions of Eclipse. Maven menu just disappears from the IDE. I hope this will be fixed someday soon.

Hi , this is the same as the problem described below - I can copy the answer here too, this should work around the problem until Eclipse release the fix

 

Hi,

This I believe is a problem with Eclipse itself (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=582183). You will likely see errors like this in the log file

"org.osgi.framework.BundleException: Could not resolve module: org.eclipse.jst.server.preview.adapter [529]"

Can you edit the following file: `configuration/org.eclipse.equinox.simpleconfigurator/bundles.info`

And add this line to the file (anywhere should work but I tested putting it at the end of the file)

jakarta.enterprise.cdi-api,2.0.2,plugins/jakarta.enterprise.cdi-api_2.0.2.jar,4,false

This should put back the missing dependency which fixed a bunch of problems (maven integration being one of them)

What do you think about?

So I downloaded 2020-06 and then try to install.  I got the message that the respository cannot be found.

Today, as part of the plugin installation through Eclipse 2020-06 R, download of most JAR files seems to work except few files whose size is above 30 MB. Even when the download was tried from browser, those files could not be downloaded fully.

The files which failed to download were:

1. com.ibm.helpwar.doc_1.0.0.v20121212_0720.jar (35,190,973)

2. com.ibm.rational.ttt.common.models.core_9.0.100.v20160212_2300.jar (34,086,041)

3. com.ibm.websphere.wdt.stubs_1.0.4.v20200826_1754.jar (44,824,252)

But we also noted that some files which were more than 30 MB could be downloded qucikly. Like:

com.ibm.websphere.v85.core_1.0.200.v20200826_1754.jar (47,107,222)

Due to this issue, we are not able to install the required plugin

The application server stops randomly and with the IBM Support we found out that the stop for the application server is sent from an local address.
It isn't stopped by myself.
If I work for ours with my applications on the WAS it works perfect, but then it could be that the server all 5 Minutes is stopped and I have to restart it.

With this output we could see that the shutdown is sent from local:

[30.08.16 10:16:52:862 CEST] 0000003b ServerCollabo A WSVR0023I: Server developer is stopping

>>As per SystemErr.log file it has following stack which tells me this is a SOAP client call :

Is there a way to get a debug log from Plugin or can you give me a hint what I have to do that this doesn't happen?
