Multi module project to deliver two different wars

I am working on a multi module Spring MVC project in which one module has to deliver a war with all dependencies and other has to deliver a war with few dependencies excluded. Is this possible? If yes how can I achieve this? The project details are as below:
The structure is:
Parent pom:
<modules>
<web-war-with-all-dependencies>
<web-ear-without-dependencies> --> Only to pack the war into an ear.
</modules>
A shared library is created in Websphere and all dependencies are added there. So, < web-ear-without-dependencies > will be deployed there.
< web-war-with-all-dependencies > will be used to build a docker tomcat image and hosted in a diff environment.
My project has to support both environments. Hence the weird requirement.

Using Maven profiles and by adding some dependencies only in some profile or setting them with scope: provided:
https://www.baeldung.com/maven-profiles
Example:
<profiles>
<profile>
<id>dev</id>
<dependencies>
<dependency>
<groupId>org.testcontainers</groupId>
<artifactId>testcontainers</artifactId>
<version>${testcontainers.version}</version>
</dependency>
<dependency>
<groupId>org.testcontainers</groupId>
<artifactId>postgresql</artifactId>
<version>${testcontainers.version}</version>
</dependency>
</dependencies>
</profile>
<profile>
<id>prod</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<dependencies>
<!-- my own library in my private repository which acts like a mock of testcontainers project. Don't ask :-) -->
<dependency>
<groupId>cz.jiripinkas</groupId>
<artifactId>fake-testcontainers</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
</profile>
</profiles>
And then you build your project using:
mvn clean install -P dev
This will put inside WAR testcontainers libraries
or:
mvn clean install -P prod
This will put inside WAR fake-testcontainer library

missing tools.jar error on Update Maven Project

When i try to update maven project I get the error that maven cant find tools.jar in JRE locations shown below:
However I have installed and specefied JDK in Windows->Preferences->Java->Installed JRE.
Is there any other place the JDK should be specified in order to resolved this tools.jar issues.
Note: tools.jar is located in lib of JDK_HOME directory and i also specified the jar as mentioned in this answer but it did not resolve issue.

Go to pom.xml and then:
<profiles>
<profile>
<id>default-tools.jar</id>
<activation>
<property>
<name>java.vendor</name>
<value>Sun Microsystems Inc.</value>
</property>
</activation>
<dependencies>
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.4.2</version>
<scope>system</scope>
<systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>
</dependencies>
</profile>
</profiles>

Maven system scope for testing purposes

I wrote a little framework for testing microservices. Now I packed my contracts into a jar which will be used to test my framework, but i don't want to deploy them to our nexus. so my pom contains
<dependency>
<groupId>mycompany.testframework</groupId>
<artifactId>test.dummy-contract</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/src/test/resources/contract-dummy.jar</systemPath>
</dependency>
now if i want to use the framework in another project (using gradle) I get this error message:
Processing of C:\Users\dam\.gradle\caches\modules-2\files-2.1\mycompany.testframework\TestFramework\0.0.1-SNAPSHOT\5859a002118d47b4237425d25dfc79ea1d7eb829\TestFramework-0.0.1-SNAPSHOT.pom failed:
'dependencies.dependency.systemPath' for mycompany:test.dummy-contract:jar must specify an absolute path but is ${project.basedir}/src/test/resources/contract-dummy.jar in mycompany.testframework:TestFramework:0.0.1-SNAPSHOT
I need the dependency for my jenkins test and build but not for "delivery". any suggestions?

I resolved it by adding the dependency to a profile wich only will be used for the test-framework and on the jenkins
<profiles>
<profile>
<id>test-dummy</id>
<activation>
<file>
<exists>${project.basedir}/src/test/resources/contract-dummy.jar</exists>
</file>
</activation>
<dependencies>
<dependency>
<groupId>de.company.testframework</groupId>
<artifactId>test.dummy-contract</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/src/test/resources/contract-dummy.jar</systemPath>
<optional>true</optional>
</dependency>
</dependencies>
</profile>
</profiles>

Java - Adding jar dependency in pom.xml

I have never built my java applications by maven. But when i am trying to do that it's giving me error.
I have created JAR file from other java application just by exporting as JAR from that application.
Now i want to add this JAR in my maven application. I don't really how to do that.
this is how i have added in pom.xml. But i don't really know what should be it's artifact id.
Seriously what is artifact id?
<dependency>
<groupId>ProjectZen</groupId>
<artifactId>community</artifactId>
<scope>system</scope>
<version>1</version>
<systemPath>${basedir}\libs\ProjectZen.jar</systemPath>
</dependency>
I am getting below error
Missing artifact ProjectZen:community:jar:1
Thanks

If it is custom jar you need to do following things
Open cmd and type following command
mvn install:install-file -Dfile=path-to-your-artifact-jar \
-DgroupId=ProjectZen
-DartifactId=community
-Dversion=1
-Dpackaging=jar
-DgeneratePom=true
Now, the “ProjectZen” jar is copied to your Maven local repository.
In pom.xml
<dependency>
<groupId>ProjectZen</groupId>
<artifactId>community</artifactId>
<scope>system</scope>
<version>1</version>
<systemPath>${basedir}\libs\ProjectZen.jar</systemPath>
</dependency>
now the “ProjectZen” jar is able to retrieve from your Maven local repository.

change
<systemPath>${basedir}\libs\ProjectZen.jar</systemPath>
to
<systemPath>${basedir}/libs/ProjectZen.jar</systemPath>
or install it in local maven cache

you should give the format as below. and the slashes used in are incorrect I suppose. Check the dependency in this format.
...
<profiles>
<profile>
<id>default-tools.jar</id>
<activation>
<property>
<name>java.vendor</name>
<value>Sun Microsystems Inc.</value>
</property>
</activation>
<dependencies>
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.4.2</version>
<scope>system</scope>
<systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>
</dependencies>

How do I invoke two different profiles in one maven command?

I have two profiles for different environments in pom.xml, I have to run mvn -PTest1 install and mvn -PTest2 install command to get these profiles in use. Can we integrate two separate maven commands in a single one (like mvn clean install)?
Here is my Pom entry
<profiles>
<profile>
<id>Test1</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.5</jdk>
<os>
<name>Windows XP</name>
<family>Windows</family>
<arch>x86</arch>
<version>5.1.2600</version>
</os>
<property>
<name>sparrow-type</name>
<value>African</value>
</property>
</activation>
<dependencies>
<dependency>
<groupId>
com.endeca
</groupId>
<artifactId>
endeca_navigation_Test1
</artifactId>
<version>
6.1
</version>
<!--<version>stable</version> -->
<scope>
compile
</scope>
</dependency>
</profile>
<profile>
<id>Test2</id>
<activation>
<activeByDefault>false</activeByDefault>
<jdk>1.5</jdk>
<os>
<name>Windows XP</name>
<family>Windows</family>
<arch>x86</arch>
<version>5.1.2600</version>
</os>
<property>
<name>sparrow-type</name>
<value>African</value>
</property>
</activation>
<dependencies>
<dependency>
<groupId>
com.endeca
</groupId>
<artifactId>
endeca_navigation_Test2
</artifactId>
<version>
6.1
</version>
<!--<version>stable</version> -->
<scope>

It will helpfull to manage hudson job using single command

Based on the documentation and discussion here, try separating profile names with a comma:
mvn install -P Test1,Test2

Mifeet's answer is correct, but in Windows PowerShell you should quote parameters, otherwise you'll get "unknown lifecycle phase" error.
mvn install -P 'Test1,Test2'

For me Mifeet's answer isn't working. I get "unknown lifecycle phase Test2". For me this is working:
mvn install -PTest1 -PTest2

Based on the maven help command
-P,--activate-profiles <arg> Comma-delimited list of profiles to activate
So you can run mvn package -Pp1,p2 to run profile id with p1 and p2
