I need to run PMD on my Jenkins server [LINUX].
Everything works fine on my Windows machine with sh.exe but when I am trying to run it on Jenkins I get the following error:
Error: Could not find or load main class net.sourceforge.pmd.PMD
I know it means that it cannot find the main class but the exact same thing works on my local env.
Both machines have java version "1.7.0_111" and pmd-bin-5.5.2. What is wrong with this? Please help.
Thank You.

Trying to run my embedded mysql based Unit tests I get an exception with this part:
Failed to instantiate [com.wix.mysql.EmbeddedMysql]: Factory method 'getEmbeddedMysql' threw exception; nested exception is com.wix.mysql.exceptions.CommandFailedException: Command 'CREATE USER 'sa'#'%' IDENTIFIED BY '';' on schema 'information_schema' failed with message 'Stream closed'
The same unit test and environment setup work on my MacBook
This machine with the error is an Ubuntu 20.04
Wix version is 4.6.2; Java 8, mysql.connector 8.0.24
I tried changing the dependencies versions and also tried with Java 11.
Run from within IntelliJ and on the command line. Same result.
Let me put the full comment I found in Github which helped me to fix this and I'm pretty sure most of the people seeing this in Ubuntu will find this as the solution:
I had this same issue with MySQL 5.7, while working on another open source project. I cloned the wix-embedded-mysql repository and ran the tests using the master branch, which also failed in the exact same way, except that I received a longer, more thorough message in the catch.
The issue was that I was on Ubuntu and did not have the ncurses 5 shared library installed. On ubuntu, I installed libncurses5 (apt install libncurses5) and everything started working (all tests on wix, and on my project).
I hope this helps resolve the issue.

I have one Linux VPS dedicated just for running a jmeter. The tests run fine, but failed requests are not written to error.jtl with SimpleDataWriter. Java error is written to jmeter.log instead.
I run the tests in non-gui mode:
jmeter -n -t om5.jmx -j results-tmp1/t3-l1-jmeter.log
The error

I cannot find what is wrong. It is only that one machine, that gives me this error. Everywhere else I try it, it works correctly.
The OS is Debian Jessie (8.5) - minimal from official repositories. I tried many different versions of java (1.7, 1.8) - currently running on the latest 1.8 (1.8.0_92-b14) and I have the latest apache-jmeter 3.0 r1743807, but previously I used 2.13 r1665067. I don't use any third-party plugins.
I didn't notice exactly when it stopped working, what change was done (some os update, maybe some change in jmx), but I have my tests in git, so I checked out older version from the date of my last full error.jtl and it is not writing the errors to jtl as well.
I reinstalled the Debian to Ubuntu 16.04 and nothing changed.
I don't know how to debug that problem, what should I do, because on any other machine I have an access to, it works fine.
I don't know if you've fixed this problem until now?
I had the same issue, and I fixed it just now.
I guess in your jmeter script, you checked the hostname to record sample result, in jmeter.log, you could find such message: jmeter couldn't get the linux Local IP, so hostname is Null, exception threw out.
So what you need to do is remove 'Save Hostname' from 'Sample Result Save Configuration' tab.
Our application is a RoR app, and currently uses JRuby version 1.7.22, and JRE 8_65. Our app is an on-prem solution, so we use JRuby to host our application on JVM at the target, Windows Server 2012 R2 system. We compile our ruby code, using
jruby -S jrubyc
This takes the .rb file and compiles it to a .class file. In the original .rb, it loads in the class file, like so.
load __FILE__.sub(/\.rb$/, ".class")
This all works with JRuby 1.7.22
Now, we want to update JRuby to 9.0.5.0, but are experiencing some problems when it comes to deploying our application. Basically, that line of code above inside of the .rb file is not working anymore, and we get the error when trying to run a rake db:setup
rake aborted!

Great. So I replace load with java_import

Still not working, no matter what I try. I looked at this post: https://github.com/jruby/jruby/issues/3018
I tried to pass the parameter
jruby -Xaot.loadClasses=true
But I get a warning saying that aot.LoadClasses is not recognized. EVEN THOUGH I see it in the properties when I type
jruby -Xproperties
I have done A LOT of research on this, and have probably have looked at everything on the internet regarding this. Any input will be greatly appreciated. Is there something I missing? I am not fully adept in Java.
Thank you.
might be the same issue as https://github.com/jruby/jruby/issues/3651
which means you'll need to wait for 9.1 or use a snapshot http://ci.jruby.org/
since, the error is slightly different you should look into reproducing with snapshot and if it fails (might be Windows related) a step-by-step reproduction might speed-up getting the issue resolved.
jruby -Xaot.loadClasses=true
this is not needed with Warbler
But I get a warning saying that aot.LoadClasses is not recognized. EVEN THOUGH I see it in the properties when I type
hmm, could you reproduce this with an empty script and no JRUBY_OPTS ?

you might want to try looking into the issue next time :) or considering getting some support

you shouldn't be missing anything - its not a Java issue ...
I am continuing to have trouble with the import.bat file for the Neo4j batch importer. I started a new thread as the original problem was resolved.
from the command prompt I run
import.bat test.db sample\nodes.csv sample\rels.csv
With some variations on the path listing for the files, including absolute paths. I continue to get the following error message
The system cannot find the path specified.
Error: Could not find or load main class org.neo4j.batchimport.Importer
I also tried running import.sh from Cygwin and in my Debian VM but keep getting the error
Error: Could not find or load main class org.neo4j.batchimport.Importer
What am I doing wrong?
Please download the zip-file, not the github clone.
This is a pre-build binary as outlined in the readme, that doesn't require that you have to have maven installed to build it.
I'm trying to call a java program from python using command line. The code is as follows:
subprocess.check_output(["java", "pitt.search.semanticvectors.CompareTerms", "-queryvectorfile","termvectors.bin","term1","term2"])
I get the following error:
Error: Could not find or load main class pitt.search.semanticvectors.CompareTerms
This happens when I run the program from PyDev (version 2.5 in Eclipse 3.7.2). However, if I run the same code from the terminal, it works and I get the result I want.
I'm almost sure that the problem is related with some configuration of PyDev and how it handles the java CLASSPATH, which is:
/Users/feralvam/Programas/semanticvectors-3.4/semanticvectors-3.4.jar:/Users/feralvam/Programas/lucene-3.5.0/lucene-core-3.5.0.jar:/Users/feralvam/Programas/lucene-3.5.0/contrib/demo/lucene-demo-3.5.0.jar:
The class "pitt.search.semanticvectors.CompareTerms" is in "semanticvectors-3.4.jar".
Any help you could give me would be really appreciated.
Thanks!
The solution proposed by #eis worked. Now, the command is:
subprocess.check_output(["java", "-classpath", "/Users/feralvam/Programas/semanticvectors-3.4/semanticvectors-3.4.jar:/Users/feralvam/Programas/lucene-3.5.0/lucene-core-3.5.0.jar:/Users/feralvam/Programas/lucene-3.5.0/contrib/demo/lucene-demo-3.5.0.jar:", "pitt.search.semanticvectors.CompareTerms", "-queryvectorfile","/Users/feralvam/termvectors.bin","term1","term2"])
