Error creating shaded jar: Problem shading JAR java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

I created fat jar(common-1.0-SNAPSHOT.jar) using maven shade plugin. It generated successfully. This common dependency include to new maven project and try to generate fat jar. But it given above error. I tried with different answers as exclude MANIFEST files. After excluding MANIFEST files it asked to exclude .class files in common.jar library.
Need I use any signing method to common library or is there any way to ignore this error.
Thank you.

Failed to load class "org.slf4j.impl.StaticLoggerBinder" in kafka stream?

I am implementing apache kafka stream application program in Java inside GCP machine. I am using kafka version 2.12
Reference URL -
https://kafka.apache.org/22/documentation/streams/tutorial
Here I am able to setup maven project. then I am able to see tree structure of stream.example in my kafka directory.In the next step, I am trying to execute Pipe java class But here I got stuck in this step.
I am able to execute mvn clean package which is giving Build success.
next command is mvn exec:java -Dexec.mainClass=myapps.Pipe which is giving warning and got stuck... see attached screenshot.
Here we can see my pom.xml file

First refer to the following link for more clarity.
StaticLogBinder
To Quote, it says
This warning message is reported when the
org.slf4j.impl.StaticLoggerBinder class could not be loaded into
memory. This happens when no appropriate SLF4J binding could be found
on the class path. Placing one (and only one) of slf4j-nop.jar
slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or
logback-classic.jar on the class path should solve the problem.
As part of solution, I will suggest you to use logback.
In maven pom.xml, add the following dependency.
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-api -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.26</version>
</dependency>
<!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-classic -->
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.2.3</version>
<scope>test</scope>
</dependency>
Create a logback.xml file and put it inside your project src/main/resources
If you do not want to use logback, then simply add the following dependency along with slf4j api.
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-nop -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-nop</artifactId>
<version>1.7.26</version>

Maven NumberFormatException when packaging

I'm getting a really weird error on my Windows PC when running mvn package (or mvn install/deploy) on a project. This error only happens on this machine, everything works fine on my laptop and other computers. I used to be able to package/install the project without problems, but now even older commits and branches throw this exception.

Console error screenshot
I'm using Maven 3.5.2 and Java 1.8.0_91. I already tried reinstalling Maven.
I found this SO post that apparently has a similar problem, but there are no solutions posted.
Anybody have an idea what could cause this?
If I run it with mvn clean install -B it produces the following error for the whole console log:

As #Oleg said in the comments, set MAVEN_OPTS=-Xss10M seems to fix the issue. It sometimes has to be called again if the error returns. All other options did not solve the problem for me.

Are you running mvn with -T option (multi-thread)?
What you describe sounds like this issue:
https://issues.apache.org/jira/browse/MNG-6382
Try to upgrade to maven 3.5.3 see if it solves your problem. The fix for the bug above is in 3.5.3

I found another way apart from Olegs solution (which also works for me) to avoid this bug:
Just pipe the output into a file and the build succeeds:
mvn clean install > build.log

killAfter deprecated warning when running exec:java

I have noticed that I get this warning every time I run my exec:java command in MAVEN.
[WARNING] Warning: killAfter is now deprecated. Do you need it ? Please comment on MEXEC-6.
How can I get rid of it? I have been searching for it, but no clue.

edit This answer is not valid anymore for newer versions (> 1.3.2) of the exec-maven-plugin.
For the down-voters please have a look at the timeline.
Jul 2014 - release of plugin version 1.3.2
Nov 2014 - posting this answer
Mar 2015 - release of plugin version 1.4.0

Update to version 1.4.0 of the exec-maven-plugin. The warning no longer appears.

choose one:
1) change exec-maven-plugin configuration in your pom by adding:
<killAfter>-1</killAfter>
2) or add command-line parameter:
-Dexec.killAfter=-1

java.lang.NoClassDefFoundError on running project with Java, but works when running with mvn exec:exec

I'm compiling and running some source code I got from a project called Structr (https://github.com/structr/structr). I'm able to run the program correctly with a maven mvn command but not using the JVM java command.
The compilation step goes well with maven clean install -DskipTests
On running the front-end (in the structr-ui directory), it goes well if using maven exec:exec but fails on java -cp target/lib/*;target/structr-ui-0.8.2.jar org.structr.Ui. I have some stack trace indicating java.lang.NoClassDefFoundError on org.structr.core.entity.AbstractNode and org.structr.core.EntityContext. What I find strange about this is that the maven pom.xml file in the exec entry we have
<plugin>

The mvn exec:exec statement looks equivalent to the java JVM statement. This question may be basically; What is maven doing differently than java, that in the maven case making the program run correctly?
Edit - additional maven and java debugging information
On mvn -X exec:exec, The output is given here http://roberthoff.com/files/mvn_exec_trace.txt
And on java -server -Dfile.encoding=utf-8 -XX:+UseNUMA -Xms1g -Xmx1g -classpath target/lib/*
;target/structr-ui-0.8.2.jar org.structr.Ui we have http://roberthoff.com/files/java_trace.txt

You have a valid question here, because according to the Maven documentation on the exec:exec goal you would need to have the <\classpath> stanza in your configuration in order to include the entire project module classpath.
However, it appears as though Maven is running the program with the fully (and properly) configured classpath for some reason.
In order to get to the bottom of the problem, I'd run Maven with the -X command line argument and carefully scan through the debug output until I found the exact command it runs. Then I'd try running it from the same directory, ensuring I am using the same Java installation and see if it works.

Notice the maven-dependency-plugin in the pom. It copies all dependencies during the package phase to target/lib folder and then they are on classpath. Following should work:
maven clean package -DskipTests
java -cp target/lib/*;target/structr-ui-0.8.2.jar org.structr.Ui
