Well, I see this as an opportunity to do that work today. If you just
figure this out now, you will have a short list of files to filter out
during the packaging step.

[Kranthi Jajula]

We could remove clj files from the jar altogether. However, the problem is we
don't know if all the clojure dependencies are AOT compiled. So, some of the
clojure files should be compiled on the fly. The problem is when dynamically
compiling clojure files whose class files already exist in the jar.

Hi Adrein,

Maven is downloading snapshot dependencies with timestamp into my local

Hi Amir,

Non-unique snapshot artifacts - without timestamp.
unique snapshot artifact - with timestamp. Maven 3 only support unique
snapshot. In maven 2, we set the false to
deploy the non-unique snapshot artifacts.

Re: how to convert unique snaphot into non-unique snaphot on downloading from nexus

[sahil_tech]

Hi Russell,
I am using maven version 3 and I have configured the maven jobs in Hudson
(mvn clean deploy) to deploy the unique snapshots artifacts into a nexus
hosted repository and for that I have configured distribution management tag
in project parent pom.xml. 
I am using maven-war-plugin to collect all artifact dependencies, classes
and resources of the web application and packaging them into a web
application archive. But, now while packaging I am getting snapshot
dependencies with timestamp in WEB-INF/lib of war file. 
To copy the flex artifacts (swf artifact) into my gui war project, I am
using org.sonatype.flexmojos:flexmojos-maven-plugin: copy-flex-resources
during process-resource phase. But, it again copying flex artifacts with
timestamp.

Re: how to convert unique snaphot into non-unique snaphot on downloading from nexus

[Adrien Rivard]

Actually this is quite surprising. I would expect the timestamp to be not
visible to the end user.
You build/deploy a -SNAPSHOT version , you ask for a -SNAPSHOT version, you
get a -SNAPSHOT in your war. Internally maven/nexus may use real timestamp
but this is not supposed to be visible. Whatever you are using to do this
must not do it correctly.

NetBeans helps quite a lot.  I've been shamefully spoiled by it and
tend to use it even just to browse code when I have no intent to
develop it.  I've used Eclipse (not STS though) and was happy to see
the back of it after losing too much time to plugins-disease.

I hear that IntelliJ is good with Maven projects too.

Re: how to convert unique snaphot into non-unique snaphot on downloading from nexus

Can you explain how you are copying the artifacts currently? You say that your 
dependencies are being packaged with a timestamp. How are you doing this? And 
then you say that you are copying the flex artifact with a plugin. What plugin 
is that?

I think that you need to explain a bit more what is going on, here.

This list does not support m2e. You'll need to ask this question on
the appropriate Eclipse list. We can help you sort out why command

Maven (command line) simply calls out to the JDK installed on your
system. You can use "mvn -X" to see the actual command that Maven uses
to call javac. If you are experiencing problems with the output of
Maven's compilation process, your real complaint is with the JDK &
javac itself, not Maven. I trust that you realize that Eclipse has and
uses its own compiler, so I would expect that you might see some
different results when analyzing class files produced by the 2
compilers.

Is it possible that javac simply reduced your import list because a)
they were not all being used or b) it swapped out the import and
replaced the short name for the class with the fully-qualified name?
Did you look at the rest of the source code that came out of jd?

We have not issued a patch version of 2.1.0 to fix the GPG signature issue,

Re: Detected Maven Version: 2.2.1 is not in the allowed range [3.0.2,)

[Stephen Connolly]

FTR, here is the standard requires I add to most of my projects:

  

(,2.1.0),(2.1.0,2.2.0),(2.2.0,)

Maven 2.1.0 and 2.2.0 produce incorrect GPG
signatures and checksums respectively.



  

  

(,3.0),[3.0.4,)

Maven 3.0 through 3.0.3 inclusive do not pass
correct settings.xml to Maven Release

  Plugin.

Re: Detected Maven Version: 2.2.1 is not in the allowed range [3.0.2,)

[Stephen Connolly]

The people who write the software you are trying to build have decreed that
you need to use a recent version of Maven in order to build correctly. They
have defined an enforcer rule to enforce their minimum maven version
requirement. The enforcer rule has kicked in and failed the build early
because you are using maven version 2.2.1 and the allowed range is [3.0.2,)

Maven has a version range syntax. briefly

[x] means only version x and no other version

[x,y] means any version >=x and <=y

[x,y) means any version >=x and x and <=y

(x,y) means any version >x and =x

(,x) means any version x

Re: Detected Maven Version: 2.2.1 is not in the allowed range [3.0.2,)

[Anders Hammar]

Highlights don't get get through when sendig from Nabble.

But the error message is saying that you are using Maven 2.2.1, but you
need to use Maven 3.0.2 or greater. I strongly suggest you use Maven 3.0.4
or 3.0.5.

Detected Maven Version: 2.2.1 is not in the allowed range [3.0.2,)

[rushikeshgarad...@gmail.com]

Hi, 
 i am very new to maven. I am trying to import hadoop source code into
eclipse. and for this i followed this link: 
http://wiki.apache.org/hadoop/EclipseEnvironment 

in this there are 2 mvn commands: 
 $ mvn install -DskipTests
$ mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true


during both command execution i came across following error

[INFO] [enforcer:enforce {execution: default}]
[WARNING] Rule 0: org.apache.maven.plugins.enforcer.RequireMavenVersion
failed with message:
*Detected Maven Version: 2.2.1 is not in the allowed range [3.0.2,).*
[INFO]

[ERROR] BUILD ERROR
[INFO]

[INFO] Some Enforcer rules have failed. Look above for specific messages
explaining why the rule failed.


Highlighted one is main area of interest which i didn't understood.(i have
installed maven2) Please can u help me in solving above query. 

Thank You

Imports of required classes have classname only without package path within the class compiled by maven

[brandenberger]

The web project composed of several modules can be deployed to the 
application server (WAS 8.5.5) and runs as expected, when built within 
eclipse (juno sp2) by the eclipse compiler. The same project built with 
maven, either through the m2e-wtp plugin or with "mvn clean install" from 
the command line, can not be run on the AppServer.

Maven build worked too, but does not anymore for unknown reason. No 
changes of configuration or programs but update of m2e-wtp.

All required configuration files bundled within the resulting project.ear 
are correct and identical to the version compiled with eclipse.
On analyzing the issue it turned out, some classes compiled by maven have 
defective import lists! 
For instance:
A *.class file decompiled with jd has the following import list:
import DocumentId;
import DocumentKind;
import IProject;
import IRequirement;
import java.io.Serializable;
import java.util.List;
import java.util.Locale;
import java.util.Map;
import java.util.logging.Logger;
import javax.faces.model.SelectItem;
We see, the list is truncated, and some imports have the class name only, 
but no package information.
If we look at the same decompiled class file, but the outcome from the 
eclipse compiler, the list look like:
import ch.commcity.monterosa.common.reports.DocumentId;
import ch.commcity.monterosa.common.reports.DocumentKind;
import ch.commcity.monterosa.ejb.IProject;
import ch.commcity.monterosa.ejb.IRequirement;
import java.io.IOException;
import java.io.Serializable;
import java.security.InvalidParameterException;
import java.security.Principal;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;
import java.util.Locale;
import java.util.Map;
import java.util.ResourceBundle;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.faces.application.Application;
import javax.faces.application.ConfigurableNavigationHandler;
import javax.faces.application.FacesMessage;
import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;
import javax.faces.model.SelectItem;
First, the latter list is longer and second the import DocumentId for 
instance  includes the full package path!
As the import list is defective, no surprise all methods look like the 
following example:
  int getFrom()
  {
throw new Error("Unresolved compilation problem: \n");
  }
instead of:
int getFrom() {
return this.from;
}
which is neither very sophisticated, but does was is expected to be done.
Question:
All dependencies declarations within the poms are the same as before. May 
a missing declaration be the origin of the problem, which before had no 
effect?
What else? I must say I had the same problem in February of this year, But 
without any conscious change (I suspect after update to sp2 of juno) it 
worked suddenly as now it stopped to work, maybe due to the m2e-wtp 
update!
The poms are unchanged and within the Kepler IDE environment maven 
compiles the code as expected. The only differences are some parts proper 
to the glassfish 3.1.2 Appserver and for the Mojarra version of JSF in 
turn of MyFaces used by WebSphere.
Any hint or suggestion is welcome.
