Importing Jar in Play Framework gives me java.lang.ClassCastException

I have created a library in java and I am trying to use it in my Java Play Framework application with Intellij.
The documentations tells me that I only need to add it to my lib folder in the project.
Yet, when I type activator run on the terminal, I have the following error(the library is seen in the Intellij and I can use it in my new code):
java.lang.ClassCastException: org.slf4j.impl.SimpleLoggerFactory cannot be cast to ch.qos.logback.classic.LoggerContext

If your jar is an unmanaged jar, that means it is not part of any sbt repo, then you need to add the following line in your build.sbt.
unmanagedJars in Compile += file("lib/your_jar.jar")

SonarQube analysis of Java module fails in Jenkins

I have created a Jenkins project to run SonarQube analysis of my product code. The workspace contains multiple modules (some in Nodejs i.e. Javascript) and some in Java. My sonar properties looks like
sonar.projectKey=product-key
sonar.projectName=product-name
sonar.projectVersion=1.0
sonar.sources=./nodejsmodule1,./nodejsmodule2
sonar.sourceEncoding=UTF-8
This works perfectly without issue and gives me a nice SonarQube dashboard. However, if I change the sonar.sources property to:
sonar.sources=./nodejsmodule1,./nodejsmodule2,./java-module-name/src/main/java
the Jenkins build fails with the following error:

When I use
sonar.sources=./nodejsmodule1,./nodejsmodule2,./java-module-name/pom.xml
The error goes away. The multi-language analysis happens. The events widget on the SonarQube dashboard for the project shows that Java and JavaScript profiles got used during the analysis. But the code analysis results don't contain anything about Java. JavaScript analysis results show up. Doesn't matter in which order I specify the sonar.sources values (i.e. JavaScript followed by Java or Java followed by JavaScript). I looked at other StackOverflow questions (e.g. Sonar analysing Maven 3 and multi language project using JENKINS). Clearly, they are specifying the location of the classes file as well. Maybe the java code is getting compiled during the Jenkins build step for SonarQube analysis so they can point to the target/classes location. When I try this (i.e. sonar.binaries=./java-module-name/target/classes), the build fails.
Based on http://docs.sonarqube.org/display/SONAR/Analyzing+with+SonarQube+Scanner+for+Maven#AnalyzingwithSonarQubeScannerforMaven-AnalyzingaMulti-languageProject, I also tried sonar.sources=./java-module-name/src,./java-module-name/pom.xml. But that brings back the exception. The exception also happens for sonar.sources=./java-module-name,./java-module-name/pom.xml, sonar.sources=./java-module-name/src/main,./java-module-name/pom.xml and sonar.sources=./java-module-name/src/main/java,./java-module-name/pom.xml.
What am I doing wrong?

The error only shows up when you include Java sources? So maybe you are using some outdated plugins on your 5.2, which are triggered on Java analysis and use the no longer available getPom() method.
org.sonar.api.resources.Project.getPom() is no longer available in SQ 5.2.
See Project.class in 5.2
The stacktrace points to surefire. Which version are you using?

Intellij Idea Maven 'cannot reconnect' error

Maybe you can help me
I got a strange apache maven's problem, when opening my project at Intellij Idea 13.
When projects was open I have no libraries at External Libraries section. And at all pom.xml files from diff's modules I see error "Cannot reconnect".
I tried to Invalidate Cache/Restart Idea, try to use Maven Reimport but problem still take a place.
But if I do mvn clean install, and deploy my projects everything works fine.
I use Maven 3.2.3. and Java 1.8.
Maven settings:

I was facing the same error and fixed it like that:
Open settings by pressing Ctrl+Alt+S and navigate to Build, Execution, Deployment | Build Tools | Maven | Importing
Check JDK for Importer and change the exact version of JDK (example : 1.8.0.250) installed on your machine from the drop-down.
After doing the same it prompts for verification and after that, the maven will be automatically updated and the project will run.
In my case, I did the same thing as the JDK which is used in the machine is different when the project is imported from a repository. These things happen when we uninstall the IDE and JDK and install the IDE and different version of JDK, the IDE automatically fetch the project which is available in the machine as before but it can not change the imported JDK.

I fixed this by changing my local Maven 3.3.9 to Idea Bundle Maven3.

Clicking on Reload All Maven Projects helped me in this scenario.

File -> Invalid Cache
might also be helpful in a scenario where IntelliJ seems to tangle up itself.

In case you are running InteliJ in WSL with X-Server (e.g. VcXsrv), a solution may be to
close InteliJ
restart the server
open Intelij
and it will be working.

I was getting this error and I fixed this error in IntelliJ by following steps:
1] close all running application(if any)
2] reimport/reload pom.xml (right-click on pom.xml -> select maven option->reimport/reload project)
3] then run your application(i.e. main file)
by following this I did not needed to delete the .m2 folder manually

I fixed this problem by removing .lastUpdated files coming from transfer error in ~/.m2
find ~/.m2 -name "*.lastUpdated" -exec grep -q "Could not transfer" {} \; -print -exec rm {} \;

In my case, I have maven runner and importer set to use Project JDK, but I managed to solve this problem by changing JDK from OpenJDK to Liberica JDK (same Java version) and it magically started working.
So for anyone with similar problem, try to change JDK to different implementation.

New Relic Android agent error with gradle

I have a project that uses the gradle build system and I'm willing to add New Relic monitoring to it.
The project (including New Relic) is working fine on Linux (Fedora 20), but won't build on my Mac development system, and gives out an error stating Agent JAR loaded but agent failed to initialize.
Here is the full log of the error:

One of the two will be used. Which one is undefined.

I have also tested with a freshly generated, bare-bones project, but it fails with the exact same error.
I use the JDK 1.7u55 version, if that matters.
Thanks

Unfortunately u55 introduced a change that breaks the New Relic agent. For now, if possible, use an older version of Java to work around this issue while building. This shouldn't affect the resulting APK. New Relic is aware of this issue and is working to fix it as fast as possible.

I emailed New Relic support, and I got the following response:
Hello,
Thanks for writing into New Relic support.
A new version of the New Relic for Mobile Apps Android SDK is in beta
and includes a fix for compatibility with JDK v7u55 and JDK v8
It is available here:
https://gist.github.com/asm/bed819fb32253e4cb072.
We're waiting to release this agent until we hear from users like you
that the SDK is running smoothly and instrumentation is now working
correctly.
Please let us know if you have any trouble installing this SDK.
I'm going to leave this ticket open so that you can send us an update.
Our automatic system will ping you to see how you're doing in a few
days and then try to close the ticket a few days after that. If it
does, don't worry, write back any time and we'll get right to helping
you.

There's a new version of new relic client available. It resolves issues that V3.361.0 had around newer JDKs and proguard. Here's what you should use to resolve the JDK problem.
classpath 'com.newrelic.agent.android:agent-gradle-plugin:3.378.0'
Paste this into your build.gradle where you have listed your dependencies. Let me know if it doesn't work.

Executing headless eclipse in command line

Following this instruction, I could run headless Eclipse plugin in side Eclipse IDE.
I've got some error log info, but I guess I could ignore it based on this post - Unable to find feature.xml in directory
Following the instruction in site, I could generate the jar file. After copying the org.eclipse.equinox.launcher.jar, I tried to execute the jar file
java -jar org.eclipse.equinox.launcher_1.2.0.v20110502.jar -application headlessHello_1.0.0.201210101430.jar
I tried
java -cp .:org.eclipse.equinox.launcher_1.2.0.v20110502.jar org.eclipse.core.launcher.Main -application headlessHello_1.0.0.201210101430.jar
to get error message
An error has occurred. See the log file

ADDED
From this site, the issue was because I didn't setup %R2_HOME%/plugins correctly. After the setup, I still get the error.
java.lang.IllegalStateException: Unable to acquire application service. Ensure that the org.eclipse.core.runtime bundle is resolved and started (see config.ini).

An instance of headless Eclipse needs to include many plugins, not just your plugin. A minimal product includes:
org.eclipse.core.runtime
org.eclipse.core.variables
<your plugin(s) here>
EDIT
I generated the product, and here is the list of plugins used by my "minimal" headless Eclipse:
I output the product, and here is the list of plugins loaded:
org.eclipse.core.contenttype_3.4.100.v20100505-1235.jar
org.eclipse.core.jobs_3.5.1.R36x_v20100824.jar

So, might I recommend that you create a product for this Eclipse application you are building, and try that. Looking for a FAQ I found this. http://wiki.eclipse.org/FAQ_What_is_the_minimal_Eclipse_configuration%3F
