How to resolve a conflict with a system scope dependency jar - maven

I have a jar that my code depends on and it is located locally on my PC.
That jar contains the 'org.apache.commons.lang3' package but an older version or a version that contains the class 'StringUtils' but without all of its methods.
In my maven pom, I am using the 'org.apache.commons.lang3' dependency also but at runtime I get the error 'NoSuchMethodError' which means that during runtime it is using the commons.lang3 version of the jar and not the one from my dependency.
Is there a way to force it to use the dependency in my pom file?
Here is how my pom looks like:
<project xmlns="http://maven.apache.org/POM/4.0.0"

CONCLUSION FROM COMMENTS:
It is not possible to remove such packages in a jar with Maven. I have to manualy edit and remove the packages from the jar file.
Thank you all for taking the time to answer!

Having trouble exporting maven javafx probject

I recently made my own version of the 2048 game in javafx. I used maven and eclipse to build the project and whenever I run the project in eclipse it works perfectly fine. However, when I exported the project into a runnable jar, the jar wouldn't run. I tried running it from the command terminal to see what was wrong. I got the error "JavaFX runtime components are missing, and are required to run this application." The thing is when I created the maven project on eclipse I made sure to add the javafxml achetype to my maven project. I thought this would ensure that javafx would work with my project. This is my first time working with maven, so any advice would be appreciated.

How to read values from .properties using maven plugin

How to read the properties from .properties file by using maven provided plugin, for one of my current project, I always used to set the properties in the <properties> tag of pom.xml, But here my requirement is, I will set the all properties in some .properties file for ex: dev.properties. It is having the following content inside it.
spring.package=org.springframework
spring.artifact=spring-core
spring.version=3.0.5.RELEASE
So, now I want to set the above properties into the pom.xml like the following:
<dependencies>
<dependency>
<groupId>spring.package</groupId>
<artifactId>spring.artifact</artifactId>
<version>${spring.version}</version>
</dependency>
</dependencies>
I gone through this link : How to read an external properties file in Maven
But it is giving the following error : Missing artifact org.springframework:spring-core:jar:spring.version
Here is the pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>
But spring-core-3.0.5.RELEASE jar is avail in maven repository.
Is there any other plugin in maven to do the same, or did I missed any additional config here.
Please correct if I am wrong.
Thanks.
First of all, when Maven reads your pom.xml, it'll immediately replace placeholders such as ${spring.version} with the actual value you specify as
<properties>
<spring.version>spring.version</spring.version>
</properties>
So changing the values later via a plugin is too late! Maven will not do this, however, if there's no value available at this time. Therefore you can remove these properties from pom.xml and let Maven plugin define them later in build lifecycle. This usually solves uses of properties overridden by plugins, but...
Second, there might be still another problem: Maven will likely resolve dependencies (including their versions) before even executing any plugin, which will prevent you from doing this whole thing. If that's the case, you can move your properties to a profile and activate a certain profile instead.
<properties>
<!-- default goes here, when no profile is used -->
<spring.version>3.0.4-RELEASE</spring.version>
</properties>
<profiles>
<profile>
<id>dev</id>
<properties>
<spring.version>3.0.5-RELEASE</spring.version>
</properties>
</profile>
<profile>
<id>prod</id>
<properties>
<spring.version>3.0.1-RELEASE</spring.version>
</properties>
</profile>
</profiles>
Please find below the corrected pom.

The problem was in -

What dependency scope for Derby JDBC drivers in intergration scope (cayenne)

I am trying to build my pom.xml so that I can automatically create my database schema when running 'mvn install'. I'm using the "maven-cayenne-plugin" to do this. This is plugin is being called (at the integration-test phase), as I can see the output. But the mojo fails with the exception: (I used the -e and -X flag to see this).
java.lang.ClassNotFoundException: org.apache.derby.jdbc.ClientDriver
(I get the same if I try and use the EmbeddedDriver and whether or not I include 'derbyclient' or simply 'derby' as my dependency).
Here's a pom.xml that should replicate the issue.
I'm using MVN 3 on Windows.

This also requires a valid cayenne "datamap.map.xml" file (in src/main/resources), here's one I made earlier:
<?xml version="1.0" encoding="utf-8"?>
<data-map xmlns="http://cayenne.apache.org/schema/3.0/modelMap"

project-version="6">
<db-entity name="TEST">
<db-attribute name="ID" type="INTEGER" isPrimaryKey="true" isMandatory="true"/>
</db-entity>
</data-map>
EDIT:
Adding more information.
The derbyclient-10.10.1.1.jar does contain the class 'org.apache.derby.jdbc.ClientDriver' (just expanded the JAR from Netbeans).
The -X flag seems to show that the CLASSPATH is correctly referencing the JAR:
[DEBUG] (f) classpathElements = [<PROJECT-PATH>\mvn\target\classes, <HOME-DIR>\.m2\repository\org\apache\derby\derbyclient\10.10.1.1\derbyclient-10.10.1.1.jar]

To ensure that the Derby driver is available during plugin execution (vs during your code compilation), you need to add it as a dependency of the plugin itself:
<plugin>
<groupId>org.apache.cayenne.plugins</groupId>
<artifactId>maven-cayenne-plugin</artifactId>
<version>3.2M1</version>
<dependencies>
<dependency>
<groupId>org.apache.derby</groupId>

<version>10.10.1.1</version>
</dependency>

....

Can anyone tell me what am I doing wrong pls?

Have you install you dependency pom to you local m2 repository?
Add scope as import to you dependency pom. Look here for more details
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.bookme.common</groupId>
<artifactId>common-dependencies</artifactId>
<version>1.0</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
Consider the following facts also
Do not attempt to import a pom that is defined in a submodule of the
current pom. Attempting to do that will result in the build failing
since it won't be able to locate the pom.
Never declare the pom importing a pom as the parent (or grandparent,
etc) of the target pom. There is no way to resolve the circularity
and an exception will be thrown.
When referring to artifacts whose poms have transitive dependencies
the project will need to specify versions of those artifacts as
managed dependencies. Not doing so will result in a build failure
since the artifact may not have a version specified. (This should be
considered a best practice in any case as it keeps the versions of
artifacts from changing from one build to the next).

i want to know what are the errors/warnings reported by findbugs.
You will find the report during the usual compile package phase created in the target directory. If you like to see a more readable output you have to use the findbugs goal in the reporting block instead of the build block.
You could also just use the findbugs eclipse plugin which will give you a nice eclipse window that points you directly to all of your bugs.
