It is used to be bug with the current folder .I have resolved the problem by creating a new folder and move my project there .

Eclipse giving java 8 support error won't start

These are my config.ini files, logs, and error I'm receiving. I was able to open and build a basic test yesterday, albeit giving binary error, but I'm receiving these errors again today trying to open eclipse. I have reinstalled java and eclipse multiple times all because of these errors. I'm running ubuntu 18.04, java 1.8.0_181, and eclipse 4.7. Can you help me get my eclipse running please?

keycloak: "Failed to read artifact descriptor" error

I'm using the Java-based Keycloak server and attempting to run the demo examples. I'm a bit of a Java hack, so please pardon my naiveté.
I'm getting the error shown below -- any help debugging and solving would be appreciated.
ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-7) Uncaught server error: java.lang.RuntimeException: org.eclipse.aether.collection.DependencyCollectionException: Failed to read artifact descriptor for org.keycloak:photoz-authz-policy:jar:3.4.3.Final
I had some trouble getting M2_HOME set so that keycloak could locate artifacts. I seem to be past that problem and now, but I'm not sure where to go with the above error. I've included some system info below. And if someone's really eager, the dockerfile is available.
I'm running v3.5.3 of maven:
$ mvn --version

I ran mvn -U clean install in the project directory, and the artifacts appear to be built correctly:

Any insight?

I was able to get the examples to run by copying the project files to the server and compiling on the server. That seems strange to me -- a fat WAR seems like it would make more sense. That is, I wouldn't expect to have to have supporting libraries compiled on a the server, but that strategy allowed me to move on. Here are the commands I ran on my wildfly server (Dockerfile commands):
# Build and install keycloak example libraries
WORKDIR /opt/jboss
USER jboss
COPY --chown=jboss:jboss _srv/keycloak-demo-3.4.3.Final ./_srv/keycloak-demo-3.4.3.Final
WORKDIR _srv/keycloak-demo-3.4.3.Final/examples
RUN mvn -U clean install
WORKDIR /opt/jboss

Cannot create Eclipse workspace

Today I downloaded Eclipse Neon. When I ran it for the first time it asked me to select a folder as my workspace. After doing this it throws me an error which redirects me to a log file inside the folder I selected to save my workspace:

Sorry for the long post. Any ideas?

You are starting Eclipse using Java 9. This currently does not work with recent builds of Java 9.
Eclipse bug 493761 describes this problem and is currently scheduled to be fixed in Eclipse 4.6.2 (Neon.2)
Until Eclipse 4.6.2 is available use a Java 8 JDK to run Eclipse.
Update:
To run Eclipse with Java 9 you need to modify the 'eclipse.ini' file in your Eclipse installation and add the line:
--add-modules=ALL-SYSTEM
as a line following the -vmargs line in the file. This adds the Java 9 module containing the missing classes.
Eclipse Oxygen.1a (4.7.1a) due for release on 11 October 2017 will have full Java 9 support.
Also see Configuring Eclipse for Java 9 in the Eclipse wiki.

Made it to work in OSX Sierra by adding the following:
--add-modules=java.se.ee
at the end of eclipse.ini

Works for me using the most recent Java 9 early access build b143 and Neon Release 4.6.0
Just add
--add-modules=java.annotations.common
to the eclipse ini after -vmargs

Adding --add-modules=java.se.ee, after -vmargs in STS.ini or eclipse.ini will solve the launching issue.
-vmargs
--add-modules=java.se.ee
-Dosgi.requiredJavaVersion=1.8
-Xms40m
-Dosgi.module.lock.timeout=10
-Xverify:none
-Dorg.eclipse.swt.browser.IEVersion=10001
-Xmx1200m
refer to the link: https://bugs.eclipse.org/bugs/show_bug.cgi?id=493761 for more information

I've just had same issue today, the issue in my case was because I was using jdk 11, good tip about the eclipse.ini file, in my case it was indicating clearly it was expecting to use jdk 8, downloaded that version, replaced the jdk path in the env params and it is working now.

Sonar runner (ubuntu) execution failed: com.mysql.jdbc.Driver

I've recently installed SONAR on a Vagrant box running UBUNTU.
Sonar service run fine, but when I try to run the sonar-runner I get an error related to jdbc connector.
I configured sonar to run with mysql database by changing the file "sonar-runner.properties":

sonar.jdbc.username=sonar

ERROR:
ERROR: Re-run SonarQube Runner using the -X switch to enable full debug logging.
From my undertanding the jdbc driver is not found. I thought that during initalisation sonar-runner will get the required jar (like it does for other libraries).
I tried to "sudo apt-get install libmysql-java" but still get the same error message.
If that's the right thing to do (which I doubt) I should maybe add the jar to my classpath, but I'm don't know where that jar is actually downloaded and how to add it to the classpath.
Any idea on how to get that solved?
Thanks!!

I was looking at the wrong place!
Issue was not comming from the runner but from SONAR itself. I had to change de sonar config file '/opt/sonar' and restart it. In the setting page I now can see that sonar is running on mysql.
I'm facing a other issue with the runner, but it is not related to the issue above.
So basicaly make sure both SONAR and SONAR-RUNNER are configured to work with mysql.

I had the same issue. Issue was that mysql JDBC connector was not in my bash_profile.
So i add on .bash_profile :
export jdbc mysql connector to classpath
export CLASSPATH=${HOME}/sonar/mysql-connector-java-5.1.23/mysql-connector-java-5.1.23-bin.jar:$CLASSPATH
Hope it could help
