Maven Shade Plugin causes duplicate jars on classpath when running integration tests - java

I have a project which includes the S3 dependency from AWS's Java v2 SDK and builds a shaded jar. I am hitting this problem when running my integration tests from the terminal. The problem is that the interceptors are added twice because the classpath contains two jars with the S3 jar: once in my shaded jar and once from the local .m2 repository. Unfortunately I don't have any control of the code that contains this issue so I need to find a workaround until the issue is fixed.
I have replicated the problem with the following pom and test class:

Collections.list(
new ClasspathInterceptorChainFactory().getClass().getClassLoader()
.getResources("software/amazon/awssdk/services/s3/execution.interceptors")
).forEach(System.out::println);
}
}
If I run the tests in my IDE then this is the output:
********** AWS execution interceptors:
jar:file:/Users/<name>/.m2/repository/software/amazon/awssdk/s3/2.5.48/s3-2.5.48.jar!/software/amazon/awssdk/services/s3/execution.interceptors
From the terminal this is the output when running mvn clean verify:
[INFO] Running com.stu.S3DuplicateJarTest
********** AWS execution interceptors:
jar:file:/Users/<name>/Development/duplicate-jars-classpath/target/duplicate-jars-classpath-1.0-SNAPSHOT.jar!/software/amazon/awssdk/services/s3/execution.interceptors
jar:file:/Users/<name>/.m2/repository/software/amazon/awssdk/s3/2.5.62/s3-2.5.62.jar!/software/amazon/awssdk/services/s3/execution.interceptors
As you can see the terminal has found two resources matching the path.
Is there anything I can do to avoid this? Is there something wrong with my configuration?


It's due to your maven configuration, shade plugin packs all dependencies into a single jar file.
Your failsafe plugin runs tests using class path from both the project dependencies (.m2/...) and that single jar file, hence the duplicated resources.
This seems to be only happening when using failsafe in command line, though. And it's fairly easy to get around, you can simply tell failsafe to not load that dependency. (It'll be available in that single jar file anyway)

Maven run unit tests without integration tests, and integration tests without unit tests

I have structure:
- test
- java
- com
- A
- service
- serviceB
- DefaultServiceBTest.java
- integration
- DefaultServiceBIntegrationTest.java
I want to run separately unit and integration tests. I am using maven surefire and failsafe plugins:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>${maven.surefire.plugin.version}</version>
<configuration>
<trimStackTrace>false</trimStackTrace>
<printSummary>true</printSummary>
<excludes>
<exclude>integration/*.java</exclude>
</excludes>
</configuration>
</plugin>
Since mvn test defaultly runs surefire:test having this configuration for maven-surefire works, and using mvn test only runs unit tests - in my case all tests that are not in integration folder.
However for failsafe i have this configuration:
<plugin>
<artifactId>maven-failsafe-plugin</artifactId>
<version>${maven.failsafe.plugin.version}</version>
<configuration>
<includes>
<include>**/integration/*.java</include>
</includes>
</configuration>
<executions>
<execution>
<goals>
<goal>integration-test</goal>
<goal>verify</goal>
</goals>
</execution>
</executions>
</plugin>
Having this configuration for maven-failsafe and running mvn verify -Pfailsafe results in first running unit tests, and then integration tests. However i dont want the unit tests to be executed with this. What is wrong with the configuration?
Thanks for help!

First you should not separate your unit tests from integration tests by using different directories. Use the existing naming conventions. Unit Test *Test.java and integration tests *IT.java...
Use the following configuration in your POM File:

By using that you can run your unit tests via:
mvn test
You can run your unit- and your integration tests via:
mvn verify
If you like to run your integration tests only:
mvn verify -DskipUTs

I am adding Jacoco Maven Plugin in POM file of Apache Tika to get the Code Coverage. But i am facing issues doing so

The Apache Tika Project has a root directory within which there is a pom.xml present. Inside the Root directory there are submodules and module named "Tika-Parent". Inside Parent module there is also a pom.xml file.
Now i am adding jacoco Maven Plugin to Tika to get Code Coverage but i am facing problems because when i add Jacoco Maven Plugin to the Pom.xml in Root Directory. It builds successfully but gives an error :"Skipping JaCoCo execution due to missing execution data file:C:\Users\adity\IdeaProjects\tika-1.20\target\jacoco.exec"
I tried adding JaCOCO Plugin to both the pom.xml files together as well as one by one each also but no result.
Also when I Perform Maven Test on the pom.xml in root directory it builds successfully running all tests.
BUT when I Perform Maven Test on the Tika-parent's pom.xml it doesnt run any tests but builds successfully.
I am attaching below the Pom.xml in root directory as well as pom.xml from Tika-parent module inside the root directory.
I am using IntelliJ Community edition ( latest version on website).

The Jacoco Plugin is present in this pom file too which is same as earlier pom file.
I tried placing in this file and building it. Didnt work. THen tried placing jacoco plugin in Root pom file , didnt work. Gives the same above mentionde error.
Please HELP!!

in my code i insert jacoco plugin in root pom under pluginManagement tag:
<pluginManagement>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.9</version>
<executions>
<execution>
<id>default-prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>default-report</id>
<phase>prepare-package</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
And in every sub-module where I do unit test I insert the following pom.xml configuration:
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
You have to enable jacoco plugin only inside java module where there are unit test.

karaf-assembly 4.0.5 - zip ard tar.gz files are not generated at the end of a successful maven build

I am an inexperienced Java and Maven developer, although I have got karaf-assembly builds to work a couple of years ago using the Karaf 3.0.1 release.
When attempting to generating a karaf-assemby 4.0.5 for a customised product build, the zip and tar.gz files are not created at the end of the maven build. The ../target/assembly directory is created each time the maven build is run and the completion status is always "BUILD SUCCESS".
I suspect this this is because the POM file has an error highlighted by the Eclipse IDE at the section for the karaf-maven-plugin directly on the line, which is as follows:
Plugin execution not covered by lifecycle configuration: org.apache.karaf.tooling:karaf-maven-plugin:4.0.5:assembly (execution: default-assembly, phase: process-
resources)
I can resolve this error in the IDE on the line by removing the "extensions" line, but then I get a "Project build error: Unknown packaging: karaf-assembly" error on the "packaging" line.

How to avoid the generation of default jar when specifying a final name?

My expectation is to create a single jar with name acme-tomcat-0.0.1-SNAPSHOT.jar but on building the project, maven is generating another one (a default one) acme-0.0.1-SNAPSHOT.jar. How can we avoid the generation of the second one (acme-0.0.1-SNAPSHOT.jar)?
Thanks

I've only used Maven a few times to build projects, and I've generated WARs for Tomcat instead of JARs, but the process should be similar.
My build looks like this:
<build>
<finalName>sb</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
The header at the top goes like this:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<groupId>org.majisto.socialbusiness</groupId>
<artifactId>socialbusiness</artifactId>
<version>0.0.2</version>
<packaging>war</packaging>
<name>socialbusiness</name>
I imagine if you switch the packaging row to JAR you should get one JAR file out of it. The finalName in the build determines the filename and I think where you have it might be the confusing part to Maven. Let me know if you have any other questions. Maven made working with Spring so much easier. Are you using "maven package" in the CLI?

By changing the build section in the profile section from
<build>
<plugins>

<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<id>default-jar</id>

to

helped me to solve this issue

Install Jar Dependency to Local Repository as Part of Maven Build Process

I have a third-party jar that is a dependency of my project. Because of business constraints, I do not have access to an enterprise or company repository, which would definitely be my preference for this issue. But regardless, this third-party jar is not available publicly, and so it is included in the web project under src\main\resources.
This is a Maven project, and so I list this third-party jar as a compile time dependency, and include in my pom a build plugin that will install the third-party jar to my local repository as part of the build process; I tell Maven to perform this goal during the validate phase of the build lifecycle, which to my knowledge would be before any other Maven phase.
However, when I run a clean install and have my local repository cleared out, the build fails due to the third-party jar not being resolvable locally or in the Maven central repository. As far as I know, I have set up the pom correctly and I should be seeing Maven attempt to install the third-party jar locally before it begins dependency resolution.
The issue is that if the dependency is listed before the jar has ever been installed locally, the build will fail due to being unable to resolve that dependency. If I remove the third-party jar declaration and run the build, after dependency resolution occurs (which is the very first thing it does after the clean), but before any other phase, it will locally install the jar and things are fine. But to my knowledge, it should run the validate phase before it collects and resolves dependencies, and so the jar should be locally installed before it's resolved by Maven. Any ideas or thoughts?

The solution from http://randomizedsort.blogspot.com.es/2011/10/configuring-maven-to-use-local-library.html is based on having a file-based, project-scoped maven repository. Thus, the library is under your source code versioning. Install is one-time manual process, rather than a something specified in the pom.xml file
Three steps:
Create a folder in your project where you will keep the repo. Say lib.
Use Maven to install your jar to the lib directory.
mvn install:install-file -Dfile=path_to_mylib.jar ^
-DgroupId=com.mylib ^
-DartifactId=mylib ^
-Dversion=1.0 ^
-Dpackaging=jar ^
-DlocalRepositoryPath=path_to_my_project/lib
3.Update your pom.xml
<repositories>
<repository>
<!-- DO NOT set id to "local" because it is reserved by Maven -->
<id>lib</id>
<url>file://${project.basedir}/lib</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>com.mylib</groupId>
<artifactId>mylib</artifactId>
<version>1.0</version>
</dependency>
</dependencies>

Saw this question while looking for a solution to a similar problem. I know it's old, but wanted to share my solution. I ended up solving my problem by using the maven-install-plugin directly:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.5.2</version>
<executions>
<execution>
<id>whatevs</id>
<phase>validate</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>${oracle.version}</version>
<packaging>jar</packaging>
<file>${basedir}/dev-setup/lib/ojdbc6.jar</file>
</configuration>
</execution>
</executions>
</plugin>
Works perfectly.

I suggest you modeling the external dependency as a separate project (think of it as a wrapper). Your current project may then be dependent on your own project that as part of its build can download the external JAR and package it into its own distributable.

Alrighty, arguing and preference aside, I did go with Sander's recommendation; it was the only one that really worked without custom Mojos, etc. I have a parent Maven project with a packaging of type pom and all it does is install the third-party jar (which could be any number of jars or dependencies) to my local repository. The parent pom:
<?xml version="1.0" encoding="UTF-8"?>

Then, I created a Maven module under the parent Maven project and used the org.apache.cxf.archetype:cxf-jaxws-javafirst:2.7.7 archetype. I simply list the third-party jar as a compile-time dependency, and it's resolved and added to the resulting war. The child module's pom:
