When I use this command:
mvn dependency:sources
Maven will attempt to download source code for each of the dependencies in my pom file (cf. Get source JARs from Maven repository). But these files are downloaded into my local cache ~/.m2.
Is there a plugin/way to create an archive into target of my project with all dependencies sources ?

I have a simple Maven project and its pom.xml has some dependencies to some local jar files inside the project structure. Now I want to upload those local jar files in JFrog Artifactory and change the pom in such a way so as to use selective dependencies from Artifactory and rest of the Pom files remains the same like it was(which includes some spring boot, Junit, surefire dependencies etc etc). How can I alter the pom file so that I can selectively download those jars from Artifactory rather than from my local machine.
I uploaded the local jars in a folder in Artifactory but unable to configure my pom/maven to download those during clean install. I tried as per the documentation in Jfrog to modify the settings.xml and include the server tag and aslo added distribution management in pom.xl to refer to the Jfrog Artifactory. But this is for all the dependencies no? I want selective dependencies to be downloaded from Artifactory.
I have a backend multimodule maven project, that is build on jenkins with mvn clean package command (maven version 3.3). After a sucessfull build I upload two of the maven subprojects target/*.jar to private nexus (using Nexus artifact uploader plugin). The jars from target folders are uploaded correctly, but the pom is not (there is no option in the plugin to upload the pom).
Then I have my webapp project, where I have dependency to the two artifacts on my private nexus. They are found and downloaded, but not the pom. Building the webapp project fails, because the dependencies are not resolved for the two jars. A warning is printed out during build:
[WARNING] The POM for <groupId>:<submodule-artifactId>:jar:1.0.0 is missing, no dependency information available
That is reasonable - I can clearly see in nexus repository that it has only jar, md5 and sha files. How should I build my multimodule maven project in a way I would be able to reference only submodules in my webapp project? Or should I upload the submodule projects poms manualy?
I am open to upload the whole backend project to nexus, but I would like to be able to add only subprojects as dependencies to my webapp.
Since you are using a private nexus, you need to specify in your maven where to look for your artifact. Usually the way to do it is to specify a repository configuration in your pom.xml as specified in this link. This will tell maven to contact your private nexus for your artifacts.
I am writing a maven plugin to control another java program (jar). This jar needs two dlls in the same directory. I would like to install the jar and this two dlls as a maven repo into local .m2 dir or a maven repository server.
I have used following command to create the local repo for the jar within my project:
mvn org.apache.maven.plugins:maven-install-plugin:2.5:install-file -Dfile=protector.jar -DgroupId=com.protect -DartifactId=protector -Dversion=10.0 -Dpackaging=jar -DlocalRepositoryPath=lib
But now i do not know how i can get the dlls in the same dir like the jar file. If i use the above command then maven creates new folder for each dll and rename it.
Anybody knows a solution?
I'm creating a base framework and distributing it as a jar file. Other developers will use this jar in the web application. others are going to use mvn install:install-file to install the jar in the local repository.
if i try to use the jar in the war , the jar dependencies(jar contains the POM file) are not available in the war. Then i included the pom file in the install command then it worked correctly.
mvn install:install-file -Dfile=path-to-file -DpomFile=path-to-pomfile
The jar file already contains pom file with dependencies,Then why do i need to include the pom file in the install command explicitly.
Is there any alternate ways to pull the dependency available in the jar(POM file) to the war file. otherwise unnecessarly i have to provide the jar and POM file to others.
Thanks,
Sampath
The war project should have its own POM file specifying a dependency on your jar project. In this way, when you build the war, your jar and all its dependencies would be pulled into the war automatically.
In order to distribute artifacts among your fellow developers you should install a repository manager, such as Nexus.
I was having a dynamic webapplication created on eclipse. I converted it to a maven project using M2E plugin. I added maven war plugin in the pom.xml so that it can create war for my project using maven build.
But when I do the build, it fails to compile few classes which has reference to the jars of my webapp/Web-INF/lib folder. These jars I can't include as dependency in pom.xml.
How can I tell maven to include Web-INF/lib jars also while building classes and creating a war?
Its not correct way of doing this , you should not put any jar manually in WEB-INF/lib folder.
And if that jar is not available in MAVEN CENTRAL REPO , then you can download it and install it in your NEXUS CENTRAL REPO (if you have any) otherwise put that jar in your local maven repository and add it as a dependency in your pom file. If you don't want to include that jar in your WEB-INF/lib then change the scope to provided otherwise leave it as default i.e compile.
During build time MAVEN will look for that particular jar in your local repo first , and if it don't find it there then it try to download from Centra Repo.
Once it is available in your local repo , your build won't break.
