I have two Maven Modules loaded in the same IntelliJ project. One module has a dependency on the other one. If I change the version of it, then my second module can't resolve the dependency anymore, except I explicitly run a mvn install first.
Can IntelliJ not resolve Maven dependencies from source modules when modules are loaded within the same project?
Sorry, I'm stupid, with correctly group and artifact ids .... works much better !

We migrated our maven code to gradle. When we build, we are getting error as Could not resolve all files for configuration ':***-war:compileClasspath'.
Could not find mockito-core.jar (org.mockito:mockito-core:2.8.9).
We are not referring to this jar itself.. neither we are able to locate in our code nor in pom...
How to figure out?
how to configure gradle to compile code if jar doesn't exist and pom exists in the repository or locally ?
If you can't work out where it's coming from and you don't use it at all, then you can exclude the dependency from all the configurations:
configurations.all*.exclude group: "org.mockito", module: "mockito-core"
If the dependency isn't appearing in the dependency report, then I'm somewhat at a loss as to why Gradle is complaining about it. The only other option I can think of is that some plugin is adding it in a non-standard way.
I'm using maven to set up a war project in IntelliJ and run in it GlassFish. The war project depends on several other modules. When I run the project in debug mode, hot deploying codechanges of the changes results in NoClassDefFound exceptions. I found out that IntelliJ tries to redeploy the module jar but GlassFish keeps a lock on it so it fails. All the classes in that module are now unavailable, causing these NoClassDefFound exceptions.
IntelliJ generates the artifacts this way: the dependent modules are all added as jar dependencies as if they were external dependencies:
Now, when I remove the jar dependencies, IntelliJ tells me it found some missing dependencies and proposes a fix to add the missing dependencies.
Fixing those dependencies will add the module compile output to the WEB-INF\classes folder.
Once deployed, IntelliJ has no problem anymore hot-deploying changed classes to GlassFish since there's no jar to keep a lock on.
Problem
Every time I make a change to any pom.xml, IntelliJ refreshes the artifacts automatically, which is fine: I definitely want to see those changes appear in the artifact. However, all modules are added as jar dependencies again.
Question
How can I make sure that IntelliJ adds the compile output of project modules to WEB-INF\classes and not to WEB-INF\lib?
I found this question but it has two problems:
There are many module dependencies so if possible I'd like to avoid specifying them all one by one in the unpack goal
IntelliJ seems to ignore this. When I add that configuration and while it works perfectly in a maven commandline build, IntelliJ still refuses to add the module compile output to the WEB-INF\classes dir
I found a bugreport that asks about the same thing but for me it's hard to believe there's no way to solve this problem. Other webapp developers using IntelliJ must have this same issue, making it difficult to hot-deploy code changes, unless I did something wrong in my pom configuration.
Now, i have a project which runs fine on my windows computer. But after I copied it to a linux computer, when compiling it reports following error:
Failed to execute goal on project alert: Could not resolve dependencies for project com.cloud.ras:alert.
The POM for com.external:commons-logging:jar:1.0.4.1 is missing, no dependency information available
The POM for com.external:freemarker:jar:2.3.4 is missing, no dependency information available
The POM for com.external:log4j:jar:1.2.14 is missing, no dependency information available
The POM for com.soa.lib:eBoxServiceCommon:jar:2.5.3 is missing, no dependency information available
but i have copied these jars to the maven repository. And can anyone give me a help?
You should NOT copy JARs in the first place. That's Maven job to resolve the dependencies for you.
It would be helpful if you explain the reason why you need to use your own groupId e.g. com.external in the first place i.e. commons-logging is from Apache but you use com.external as its groupId.
If you really insist on wanting to use your own groupId, at least download the JAR and install it using Maven. See here:
http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html.
I have successfully imported a parent pom with child modules into IntelliJ. The child modules have dependencies between themselves and IntelliJ has correctly set up the classpaths so that changes to module A are reflected in module B. However these dependencies are not maintained when I execute a maven goal in IntelliJ (compile, jetty:run etc). Here is my structure:
client_libs
-- servlet-filter
-- filter-example
filter-example depends on servlet-filter. However when I run maven compile on filter-example I get:
The POM for com.cloudseal.client:servlet-filter:jar:1.0-SNAPSHOT is missing, no dependency information available
I can work around this by manually installing servlet-filter into my local repo before I execute a maven goal but obviously this is not ideal. How can I get IntelliJ to maintain the relationships between the modules when I execute a maven goal?
You shall be able to just run mvn package but from place/path where your parent pom is.
If this's not working for you, please post your pom.xml files.
I am trying to move my MyEclipes projects to maven. But of course there are problems. After creating a web priject I get missing jar files - about 5
org.springframework.security jar files e.g. org.springframework.security.ldap-3.0.5.RELEASE
show as missing in the jar build path. They are not in the corresponding .m2 directory. I un-installed ME4S, and deleted .m2, which force .me to be rebuilt on re-install, but it has the same problem.
How do I fix this?
It would be very helpful to understand how the .m2 process works - where is this coming from and how is it controlled?
I am not sure about the MyEclipse part, but this seems to be a pure maven question.
Maven (2/3) uses the pom.xml. This file describe your project. In that file you should define a list of dependencies (which can have their own dependencies and so on).
Maven read the pom.xml and build the classpath accordingly using direct and transitive dependencies.
You can use the mvn dependency:tree command to see how your classpath is built.
