Hi!
Myeclipse 7.0.1 on linux is ignoring <scope>provided</scope> directives in dependencies when deploying to a server, e.g. container provided jar’s are copied to WEB-INF/lib. This applies to packaged as well as exploded mode. When exporting the project to .war, the provided scope is honored.
Is there a workaround other then deploying manually or deleting the offending jar’s from WEB-INF/lib by hand?
Thanks, regards,
Thorsten… and this forum is silently cutting the subject line to 50 chars. Some would think it good practice to not allow more then 50 chars being entered instead of just throwing away user input. 😉
Can you tell me what Jars exactly get deployed this way? Note: MyEclipse will deploy JSF jars to Tomcat since otherwise an application will not work.
My test:
1. Added<dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.14</version> </dependency>Log4J jar is deployed.
2. Added:
<scope>provided</scope>The jar is not deployed, as expected.
Hello, Eugene.
You are right in your example everything works fine. However, the problem still exists. These are the steps how to reproduce it:
1. Create a new Java Maven Project named say “UtilityProject”. Leave default values provided by wizard.
2. Open pom.xml of the created UtilityProject and ensure that it has the following “coordinates”:<groupId>UtilityProject</groupId> <artifactId>UtilityProject</artifactId> <version>0.0.1-SNAPSHOT</version>3. Create a Web Project with Maven support named “WebProject”.
4. Open pom.xml of the WebProject and add our UtilityProject as a dependency with node scope set to “provided”:<dependency> <groupId>UtilityProject</groupId> <artifactId>UtilityProject</artifactId> <version>0.0.1-SNAPSHOT</version> <scope>provided</scope> </dependency>5. Deploy the WebProject on the server. I tried both Tomcat and JBoss AS. The result is the same, the WebProject’s WEB-INF/lib folder contains a file with name utilityproject_classes.jar.
P.S. I tried this example on Windows XP and Linux Ubuntu. I managed to reproduce the problem in both cases.
I can’t reproduce the problem either under MyEclipse Build id: 7.0-20081201.
But, here are some tips I’ve found when troubleshooting scope-provided dependencies:
Have you done a clean from the project menu, followed by a redeploy?
Does mvn dependency:tree list the scope as provided (i.e. has another dependency overriden your scope) or even better what does “mvn install” have in the war’s WEB-INF folder?
Have you remove all files from [PROJECT]\WebRoot\WEB-INF\lib (or src/main/webapp)? (the project WEB-INF\lib, not the one on tomcat)
Alternatively, is there a “Referenced Libraries” build-path container visible.
Under the source tab in the java-build path (of the project properties), if it says the output folder is target/classes, then you need to re-import your project (usual causes are updating the project configuration [directly or indirectly] or have a invalid pom configuration [e.g. missing <packaging>war</packaging>].
There is always the workaround of using “mvn clean install” from the command line (outputs to the target folder of your project). If that is having the same problem, then the artifact jar is your project’s WEB-INF\lib.
Hey, thanks for help. Sorry for the delay. I’ve been trying to install MyEclispe 7.0 (I am having some problems with Pulse). It turned out that I used MyEclipse 6.6 when post my reply on this thread. I will try what Allen suggested as soon as I get MyEclipse 7.0 installed.
Well, don’t want to be annoying, but I still have an “UNEXPECTED JAR FILE” in the WEB-INF/lib folder of the packaged by MyEclipse 7.0 war file (despite the fact that this UNEXPECTED JAR FILE corresponds to a dependency with scope “provided”).
Allen, thanks for your tips. These are the answers for your questions:Have you done a clean from the project menu, followed by a redeploy?
Yes, I have cleaned all the project before redeploying.
Does mvn dependency:tree list the scope as provided (i.e. has another dependency overriden your scope) or even better what does “mvn install” have in the war’s WEB-INF folder?
Yes, mvn dependency:tree lists the dependency as “provided”.
Have you remove all files from [PROJECT]\WebRoot\WEB-INF\lib (or src/main/webapp)? (the project WEB-INF\lib, not the one on tomcat)
My “[WEB_PROJECT]/WebRoot/WEB-INF/lib” is empty.
Alternatively, is there a “Referenced Libraries” build-path container visible.
The WEB project does not have “Referenced Libraries”. It only has “JRE System Library” and “Maven Dependencies”.
Under the source tab in the java-build path (of the project properties), if it says the output folder is target/classes, then you need to re-import your project (usual causes are updating the project configuration [directly or indirectly] or have a invalid pom configuration [e.g. missing <packaging>war</packaging>.
The output folder of my WEB project is “[WEB_PROJECT]/WebRoot/WEB-INF/classes”. The pom.xml file has <packaging>war</packaging> defined.
I now use MyEclipse 7.0 (build 7.0-20081201), but as you can see still have exactly the same problem. What I am doing wrong? Any ideas?
One more thing… I also want to mention that if I package the WAR file manually (i.e mvn clean package) everything works fine — no “provided” dependencies in the lib folder (i.e expected behavior).
Denis,
Is it possible for you to share this project with us so we can pull it into our dev environment and step right through the code that is getting triggered and see what is going on?
Absolutely, how can I do that? I might send the whole workspace through email for example. Can you please tell me where to send it to?
