I tried to install two versions of Neo4j community edition (4.2.0-SNAPSHOT and 4.1.4-SNAPSHOT).
Both are failing with these errors:
[ERROR] Failures:
[ERROR] HostnamePortTest.testGetHostAddressUnknown:121 Expected java.net.UnknownHostException to be thrown, but nothing was thrown.
[ERROR] HostnamePortTest.testMatchesIPWithHostUnknown:267 Expected java.net.UnknownHostException to be thrown, but nothing was thrown.
[ERROR] HostnamePortTest.testMatchesKnownHostWithHostUnknown:332 Expected java.net.UnknownHostException to be thrown, but nothing was thrown.

[INFO]
[ERROR] Tests run: 222, Failures: 5, Errors: 0, Skipped: 0
I can finish the installation with skip tests flag enabled but later when I try to connect to Neo4j I'm getting these errors:

Can someone help, I'm not sure what are these errors about?
Thanks,
Joe
It looks like Neo4j community edition works fine even though test cases produce errors. I'm still not sure where are those errors coming from, they don't make much sense.
As for the second part it looks like Neo4j Java driver is printing INFO messages as ERROR messages to console ([error] INFO: Closing driver instance 1496355635). Again I'm not sure why.
My solution was to skip test cases during installation with this command:
mvn install -DskipTests

First off, I did notice that there are multiple similar questions on this topic in SO. (e.g: Tomcat v9.0 Server at localhost failed to start in Eclipse). The error message and console messages are quite similar. I have tried the suggestions from that question as well as from a few others - but to no avail.
Secondly, the twist is that this works perfectly fine from a different eclipse workspace on the same laptop. The two eclipse projects are virtually identical (copy/paste). I'm hoping someone can help me figure out as to why this is so. I am more than willing to provide additional information (code, screenshots etc.) - but I don't know where to start.
A little bit of history/ context:
My web-projects suddenly started running into this problem (not sure what I changed) and after being unable to resolve it, I un-installed and re-installed eclipse as well as tomcat on my laptop. I also started with a fresh eclipse work-space. The projects in the new work-space work fine. Those in the earlier work space still show the same error.
It would indeed be very helpful to understand as to what is causing this.
update: I'm adding the error message and the console logs as indicated #Tim Biegeleison in the comment below.

I download the 2020-03 Eclipse Platform Runtime Binary (v4.15 from eclipse-platform-4.15-linux-gtk-x86_64.tar.gz), then invoke the p2 director to install CDT package, but I'm always getting multiple caught exceptions of http://download.eclipse.org not responding (http/https switch doesn't have effect on this).
./eclipse -application org.eclipse.equinox.p2.director -profile SDKProfile -noSplash -roaming -repository http://download.eclipse.org/releases/2020-03,http://download.eclipse.org/releases/2020-03/202003181000/,http://download.eclipse.org/eclipse/updates/4.15/,http://download.eclipse.org/releases/latest,http://download.eclipse.org/tools/cdt/releases/9.11 -installIU org.eclipse.cdt.feature.group/9.11.0.202003091030
I tried it with Oracle JRE 8 and with Oracle JDK 14, I tried it on Debian and RHEL machines, tried different network connection (3 different IPS locations), removed all other plugins I install to nail it down to the CDT plugin. I do not know why or what is causing it, and searching for this problems shows to people that ISP fixed or some similar solution. While mine is consistent for about a year. I always eventually finishes, but it will will print out multiple messages:
Installing org.eclipse.cdt.feature.group 9.11.0.202003091030.

Using the HTTPS repositories has similar output:

It's not critical as it eventually completes and the end result works, but I would like to understand it better what is happening, what has effect on this behaviour. When I shrink the list of repositories to these two, it will still install, but the messages will be present:
http://download.eclipse.org/releases/2020-03,http://download.eclipse.org/tools/cdt/releases/9.11
Is there maybe a resource/documentation which probably I missed and is explaining more in the detail what is happening and why?
I am facing this issue on my WebLogic 12 C, where an application gives this error
java.lang.ClassNotFoundException: weblogic.jms.common.ResourceAllocationException
The jar for the above class is wlclient.jar and it's not included in my application and I checked the managed server classpath ,it's not included there as well.
Funny thing is if I try adding the wlclient.jar in the setDomainEnv.sh as PRE_CLASSPATH hoping it will pick up the jar , I get the below error and managed server fails to start

I found if I add the classpath fully like below then the managed server gave error on startup
,
PRE_CLASSPATH="${DOMAIN_HOME}/lib/wlclient.jar"
export PRE_CLASSPATH
But if I add the classpath as below , then it worked.
PRE_CLASSPATH="${DOMAIN_HOME}/lib/"
export PRE_CLASSPATH
individually servers are run well,Please ANY thoughts on this[i created two severs but when i try to run simentaneously it shows this error][1].
i already using running first server as :play run 9000
2nd sever as play run 9001
is this correct?

My guess is that you are trying to run them on the same port.
Add -Dhttp.port=9001 to one of them.

Add this before creating a driver. This will avoid showing the port info.

You can safely ignore the INFO messages which is not actually an issue or error.
