We are trying to install maven on aws. As part of our instructions after installing the file/updating environment variables, we need to go on cmd, remote to C:\ then put maven "plugin:download" to download the required jars! but I'm faced with this error.
can someone help?
CMD error
You probably have network connectivity issues. Consider setting your proxy configurations for Maven: https://maven.apache.org/guides/mini/guide-proxies.html

An error occurred during installation: No such plugin: cloudbees-folder (While installing Jenkins suggested plugins getting the error on windows 10)
This work for me:
http://localhost:8080/restart
OR
service jenkins restart on my Ubuntu
For Windows users, restarting the Jenkins service will resolve the issue.
For that Open Task Manager (Ctrl+Sft+Esc) -> Services -> right-click on Jenkins service and choose the option restart
If you are using the Jenkin's image in Docker if you see this error just try to execute the below command:
http://localhost:8080/safeRestart
you will get a prompt do you need to restart don't click on yes just ignore then start creating your jobs by clicking on NEW, it's just a plugin
For the docker version
1-open the browser
2- write your_ip_address:your_docker_port/restart
Note: you must have the password generated by your Jenkins server
if you do have click here
As a comment suggested: always look for official images mentioned here jenkins.io/download.
I faced the same issue when using the docker image jenkins:2.60.3, it turned out that this image isn't an official one, the official images look like jenkins/jenkins:<something>, you can find them here: https://hub.docker.com/r/jenkins/jenkins
If you are behind a firewall (local or through a VPN), there's a good chance that it's failing to download files correctly.
Try installing from another location or disabling the VPN.
Or request your network admin to allow the connections.
When I initially started my server while on a VPN there were two connection failure stack traces.
I am running Jenkins on Ubuntu in AWS.
I had this initial problem after booting up the box.
Ran the following:
sudo service jenkins restart
All working for me now.
Check the Context Path in tomcat for Jenkins that you have given during deployment and then restart/safeRestart from that path.
For example: The Path in the below screenshot is "/jenkins", So the restart URL will be
http://localhost:8080/jenkins/restart OR
http://localhost:8080/jenkins/safeRestart
I just Unchecked all the plugins and clicked on the install button. After that, it successfully takes me to the inside.
Just restart the machine. It successfully worked for me.
I am getting an error while installing the features.
error executing command: error restarting bundles
Initially, it worked fine for some of the features but then it suddenly started throwing this error.
Any suggestion on this would be appreciated.
if you clean karaf, you can resolve the issue, by running the following command, you can clean the karaf.
./karaf clean
When OpenDaylight moved to karaf 4 there were problems identified with
installing features in the karaf shell one after the other. I think
you are hitting that problem.
you can try listing out all the features you want in the featuresBoot
variable of the etc/org.apache.karaf.features.cfg file.
You may also have some success trying to install on the karaf shell with
the following flag --no-auto-refresh, like this:
feature:install --no-auto-refresh odl-l2switch-switch
Also, as sridhar reddy noted, if you use "karaf clean" to start karaf it will
wipe the data/ folder (and more) so that old loaded features will not come
back in on startup and you will start "clean".
When trying to deploy my application to the Google App Engine server I get the following error:
Cannot get the System Java Compiler. Please use a JDK, not a JRE.
All solutions I've seen for this involve editing an eclipse configuration file, but I'm not using eclipse. I'm executing appcfg.cmd from the dos prompt. I have a jdk installed and my JAVA_HOME is pointing to it:
c:\program files\java\jdk1.6.0_43
Obviously appcfg.cmd is not looking at JAVA_HOME. It must be getting the JDK location from somewhere else.
Any ideas?
As noted in the comments: Make sure the JDK is FIRST in your PATH.
I had the same issue with appengine sdk 1.8.1 and sts 3.6.4.
I tried adding vm properties to sts.ini file, added %JAVA_HOME% to the beginning of the path variable. But nothing was working as I kept getting the same error.
Cannot get the System Java Compiler. Please use a JDK, not a JRE
Then I found the issue was with Windows\system32\java* file. The appengine was reading the java from Windows\system32.
There were three files.
java.exe
javaw.exe
javaws.exe
I replaced these files from JAVA JDK home as they were from JAVA JRE home during installation. After that, I restarted my sts and everything worked fine as I am able to deploy without issue.
I upgraded today to GAE 1.7.4 and on trying to deploy I see following error:
Preparing to deploy:
Created staging directory at: 'C:\Users\VSKUMA~1.ST-\AppData\Local\Temp\appcfg4811921061542689032.tmp'
Scanning for jsp files.
Compiling jsp files.
java.lang.RuntimeException: Cannot get the System Java Compiler. Please use a JDK, not a JRE.
I already have JDK pointing in the build path and this all was working fine till GAE 1.7.3
I cannot uninstall the existing GREs for some reasons.
For me at least, forcing Eclipse to use a different vm itself worked. Add, for example:
-vm
C:\Program Files\Java\<jdk1.6.0_38>\bin\javaw.exe
to the first two lines* of the eclipse.ini file and restart Eclipse.
*Thanks to Andre
finally i uninstalled jre manually and this only helped me to get through this
Yes #Vik, i had this problem when updating to GAE 1.7.3 and the solution to the problem is to reinstall the JRE... but! if you are working with Eclipse, and this doesn´t work either, try reintalling the whole IDE. (i had to do so, and it worked for me ¬¬ )
Unable to locate the JVM for project scrapbook1. Please verify that you have a project-level JVM installed by inspecting your project's build path.
I get this error in the console when i debug my web application in Eclipse
Please help !!!
Have you installed JVM/JDK? Assuming you are on Windows, go to command prompt and type
set %JAVA_HOME%
This should the path to JDK. If it does not, then you need to install JDK and set the parameter JAVA_HOME in environment variables.
Once you have installed JDK and set the variable, check following: Go to Java build path of your project (Hit Alt+Enter on your project) and see if it shows JRE system library as shown in image:
I had the same problem, but the JDK was installed. I just updated all the libraries 'Help -> Check for Updates' and then restarted Eclipse. After that, everything worked.
