Maven : Packaging Jar on local filesystem, but not in WAR file. - java

We are working on a Spring-MVC project in which we use Maven as a dependency management tool, deployed on Apache Tomcat. Currently, we are also integrating Stanford parser, and adding the model libraries is increasing our WAR file's size from 192Mb to 600Mb.
This presents us a problem as we are still in development, and we do deployments on our test system more often and would like to reduce the delay it takes in uploading files.
Is there any way, that we can add those JAR's on our local file-system from which they are referred but not included in the WAR file? Thank you.

Did you try scope provided - it should be excluded from the war.
Documentation project object model

You could move these big libraries in the the Tomcat lib folder and don't provide them in the packaged war by specifying them as provided in Maven.

remove a jar file from third party war dependecy

so I want to exclude one jar file from a third party war dependency due to cve issues.
I tried a lot of ways like overlay exclude, but it did not help.
Basically, i just want maven to remove that jar transitive dependency in the war file.
Here is my current code:
<dependencies>
<dependency>
<groupId>org.apache.solr</groupId>
<artifactId>solr</artifactId>
<version>4.10.3</version>
<type>war</type>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.2.2</version>
<configuration>
<overlays>
<overlay>
<groupId>org.apache.solr</groupId>
<artifactId>solr</artifactId>
<excludes>
<exclude>WEB-INF/lib/commons-fileupload-1.2.1.jar</exclude>
</excludes>
</overlay>
</overlays>
</configuration>
</plugin>
</plugins>
</build>
But when I check the solr war file, the commons-fileupload-1.2.1.jar is still there. I am kind of lost now.

Optional jar inclusion in fat jar in maven plugin

How to create a fat jar with specific dependencies.
I have spark project which need 2 external jar which I wanted to add in application jar. when I am creating executable jar then no dependency is included in jar and when I create fat jar all the dependencies are getting added including spark etc.. I wanted to add only those 2 jars in my jar. below is the pom file I created using maven assembly plugin.
<dependencies>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.11</artifactId>
<version>2.2.0</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-sql_2.11</artifactId>
<version>2.2.0</version>
</dependency>
<!-- Below dependencies need to be added in Application jar -->
<dependency>
<groupId>netacuity</groupId>
<artifactId>common-netacuity-db</artifactId>
<version>3.1.2</version>
</dependency>
<dependency>
<groupId>netacuity</groupId>
<artifactId>common</artifactId>
<version>2.1.1</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4.1</version>
<configuration>
<!-- get all project dependencies -->
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<!-- MainClass in mainfest make a executable jar -->
<archive>
<manifest>
<mainClass>com....App</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<!-- bind to the packaging phase -->
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
You can use the scope for this. By default scope is compile and so all the jars will be included when you package it.
To include a jar you can either provide scope as compile and keep the default
<dependency>
<groupId>netacuity</groupId>
<artifactId>common-netacuity-db</artifactId>
<version>3.1.2</version>
<scope>compile</scope>
</dependency>
To exclude the jar, you can change the scope to provided. These jars should be available during runtime.
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-sql_2.11</artifactId>
<version>2.2.0</version>
<scope>provided</scope>
</dependency>

maven package class not found selenium Web Driver

I'm creating maven application where I'm getting information from website.
I created maven package, but when I run jar using command:
"java -jar app-1.0-SNAPSHOT.jar" I get this error:

Please help me find out what is wrong. Thanks!
there may be a chance of version mismatch as follows:
Starting with 2.53.0 you need to explicitly include HtmlUnitDriver as a dependency to include it. Version number of the driver is now tracking HtmlUnit itself.
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>htmlunit-driver</artifactId>
<version>2.53.1</version>
</dependency>
Keep same versions of Selenium-Java and HTMLUnitDriver.
OR
There might be a dependency on selenium-server-standalone.jar
If you are using DefaultSelenium (or the RemoteWebDriver implementation), you still need to start a Selenium server. The best way is to download the selenium-server-standalone.jar from the Selenium Downloads page and just use it. Furthermore you can also embed the Selenium server into your own project, if you add the following dependency to your pom.xml:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-server</artifactId>
<version>3.0.1</version>
</dependency>
Note: Be aware, that the selenium-server artifact has a dependency to the servlet-api-2.5 artifact, which you should exclude, if your project will be run inside a web application container.

dbcp jar added automatically into project

I'm working on a maven based web project. In one module that generates .war file i have some dependencies in POM file, some jars are added to WEB-INF/lib folder. i don't have added jar: commons-dbcp-1.3.jar into POM nor in lib folder, but when i build my project using maven, commons-dbcp-1.3.jar added .war file also i can view it to lib folder in target directory.
Can anyone help me to explain how this jar is being added to war or lib folder in target directory.
I have also checked the "build path" and this jar is not added as an external jar.
I'm using Eclipse(Indigo).

This jar can possibly be one of the dependencies for running your project and Maven automatically downloads and packages the required dependencies(jars) for the project at the time of compilation and packaging.
DBCP commons jar is provided by Apache for maintaining the pool of connection objects . It is basically used in the applications involving database connections where many users can simultaneously try to access the DB(eg: Web Base Applications involving DB operations) to improve the performance of the application and the system.
If you don't wish to bundle this jar with your package and such a capability will be provided by the web container where your application will be deployed(connection pooling), you can set the scope of this dependency to be 'provided'.
The scope you should use for this is "provided". This indicates to Maven that the dependency will be provided at run time by its container or the JDK, for example.
Dependencies with this scope will not be passed on transitively, nor will they be bundled in an package such as a WAR, or included in the runtime classpath.

How to exclude dependencies in Maven <reporting> plugins?

How do I exclude dependencies from a reporting Maven plugin? The cobertura-maven-plugin annoyingly pulls in ch.qos.logback:logback-classic which causes mulitple SLF4J bindings warning during build and run. I tried inserting <dependencies> with <exclusions> to the plugin but maven for some reason does not allow that in the <reporting> section. Any help is appreciated. The relevant POM is below.
<reporting>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-project-info-reports-plugin</artifactId>
<version>2.8</version>
<configuration>
<dependencyLocationsEnabled>false</dependencyLocationsEnabled>
</configuration>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.7</version>
<configuration>
<formats>
<format>html</format>
<format>xml</format>
</formats>
</configuration>
</plugin>
</plugins>
</reporting>
This is old but I'll give my solution in case someone else has this exact issue. In my poms I inserted the following
<dependencies>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.7</version>
</dependency>
</dependencies>
Inside the definition for my Cobertura plugin.
Cobertura is using 1.1.7 anyway (in my case) check your artifacts to confirm, you just need to explicitly tell maven to pull that version when creating the plugin otherwise it will still pull the conflicting version and display the error
I have solved this issue including the "scope" tag inside logback dependencies.
This is my POM section:
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>${logback-classic-version}</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>${logback-core-version}</version>
<scope>runtime</scope>
</dependency>
