Log4J - cannot find symbol - method trace(String)
Hi everyone, I have the following dependency in my project's POM: ... dependency groupIdlog4j/groupId artifactIdlog4j/artifactId version1.2.17/version /dependency ... The artifact is downloaded to my local repository, but, during the compile phase, the following error is emitted and the build process is aborted: [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project dbtoixattrdt: Compilation failure: Compilation failure: [ERROR] d:\prace\dbtoixattrdt\DBToIXATTRDT-TRUNK\src\main\java\dbtoixattrdt\TraceLogAspect.java:[19,8] error: cannot find symbol [ERROR] symbol: method trace(String) [ERROR] location: variable logger of type Logger This error message does not make much sense, as the trace method should be available on the Logger class in Log4J version 1.2.17. What can be wrong? Thanks in advance, Dušan

Are you using Eclipse? What does the editor say about the error? Quick fix? If you can download Eclipse/STS which includes Maven support and load up your project, you will find the error pretty quickly.

Re: Log4J - cannot find symbol - method trace(String)
And for another thought: maybe of your other dependencies include the
org.apache.log4j.Logger class but with a different version.
Check with maven copy dependencies and a grep over the contents of all
the jar files.

Re: Log4J - cannot find symbol - method trace(String)
Thank you all, I have finally managed to find the root of the problem.
Nick's warning about the possibility of a different Log4J version as a
transitive dependency got me thinking and I tried disabling the
dependencies, one at a time, to see what would happen. The errors
disappeared after disabling a custom 3rd party library that I have
installed to my local repository manually and after inspecting its contents
it turned out that there is an older Log4J version packed inside the JAR
along with the rest of the library.
Thank you once more for all your quick responses,

We make a lot of aggregation jars that are used in the same way. http://blog.artifact-software.com/tech/?p=121 describes how we handle a similar need to produce skinny wars that use libraries in Tomcar/shared or tomcat/lib to avoid copies of the same code in multiple jars. Our LMS project has over 80 Maven projects that produce a variety of jars and wars. Many of these share the use of large libraries such as CXF, Spring and Apache commons that can be shared through Tomcat's classloader rather than duplicated in each war. There are some other notes about Maven on our blog that you might find interesting. I would prefer an installer to get the shared libraries into tomcat/lib but that is another issue.

Is there anything about your build that is different from the thousands of projects that use Maven to build Tomcat applications? Have you looked at using Maven to build an installer with izPack. This will let you use Maven to build the components and use the maven izPack plug-in to build a user-friendly deployment tool that lets a system admin install all of your components in the right places with the required permissions, initialization, etc. that may be required.

I don't have time to look at code and projects for free. If you need consulting to move forward, there are others here that do Maven for a business and can help you better than I can. Have you tried making the red5 scope provided. What does this do to your build? Does it get eliminate the red5 classes from your jar so that it only appears in the assembled war as a resource? To make life simpler, remove all code from the war project and put it into a separate project that makes a jar that the war depends on. This will make it clearer when you need red5 to compile your code and when you need it to build a deployable war. It will have scope provided as a dependency in your jar project.

Finding unused dependencies
Hi Users, I wonder whether there's an easy way to find unused dependencies for a module.I have a module which has bunch of dependencies, I have removed most of them but I wonder whether there's an easy way rather manually doing it. I there a way to get a warning about unused dependency in a pom file for a given module. Thanks Lahiru -- System Analyst Programmer PTI Lab Indiana University

Netbeans maven project with invalid POM/classpath problem
Hi , I am new to Maven and Glassfish (and pretty new to Java and Netbeans!) and am struggling to build a JPA based 'injection' project that I want to run as an application client (using Glassfish appclient) to inject rows from an Oracle db table into a JMS queue. Specifically the problem is: When I build the 'injection' project' I get an invalid pom message but it builds. The POM for com.oracle:ojdbc6:jar:11.2.0 is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details Running it with appclient however it fails as I get the following error: org.eclipse.persistence.DatabaseException. Exception description: Configuration error message - Class [oracle.jdbc.Oracle driver] not found. Browsing the local Maven repository using Netbeans I find the following if I right-click on the ojdbc 11.2.0 jar and select 'View Details' -- org.apache.maven.project.InvalidProjectModelException: 1 problem was encountered while building the effective model [FATAL] Non-parseable POM C:\Users\mcedward\.m2\repository\com\oracle\ojdbc6\11.2.0\ojdbc6-11.2.0.pom: end tag name /body must be the same as start tag meta from line 142 (position: TEXT seen ...!-- End of carousel script --\n/body... @453:8) @ line 453, column 8 for project for project at org.apache.maven.project.DefaultMavenProjectBuilder.transformError(DefaultMavenProjectBuilder.java:193) at org.apache.maven.project.DefaultMavenProjectBuilder.buildFromRepository(DefaultMavenProjectBuilder.java:240) at org.apache.maven.project.DefaultMavenProjectBuilder.buildFromRepository(DefaultMavenProjectBuilder.java:251) at org.apache.maven.project.DefaultMavenProjectBuilder.buildFromRepository(DefaultMavenProjectBuilder.java:258) at org.netbeans.modules.maven.repository.ui.ArtifactMultiViewFactory.readMavenProject(ArtifactMultiViewFactory.java:231) at org.netbeans.modules.maven.repository.ui.ArtifactMultiViewFactory.access$000(ArtifactMultiViewFactory.java:104) at org.netbeans.modules.maven.repository.ui.ArtifactMultiViewFactory$1.run(ArtifactMultiViewFactory.java:187) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1423) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:2033) -- It says this could be because : - I'm offline (but I'm not) - The repository content is wrong - no reason to suppose it is - The project or dependences cannot be resolved for the given set of repositories - no reason to suppose this either - 'Find Usages' seems to give the right answer - bug in the Maven or Netbeans codebase -? Hence posting to Netbeans and Maven forums I have successfully compiled and run an early version that just loads text to JMS so have got appclient to run successfully. I now want to use JPA to read the db. I have a separate Maven 'persistence' project that defines the persistence entities and have used this successfuly with another 'generation' project that generates the database table content in the first place. When I build the persistence project I get the same 'Invalid POM' message but it still works fine when included as a compile-time dependency in the 'generation' project. The persistence project has the following POM: --- ?xml version=1.0 encoding=UTF-8? project xmlns=http://maven.apache.org/POM/4.0.0; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xsi:schemaLocation=http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd; modelVersion4.0.0/modelVersion groupIdcom.oracle/groupId artifactIdcepdemodatagen/artifactId version1.0-SNAPSHOT/version packagingjar/packaging dependencies dependency groupIdorg.eclipse.persistence/groupId artifactIdjavax.persistence/artifactId version2.1.0/version typejar/type /dependency dependency groupIdcepdemo/groupId artifactIdcepdemopersistence/artifactId version1.1-SNAPSHOT/version typejar/type /dependency dependency groupIdcom.oracle/groupId artifactIdcepdemopersistence/artifactId version1.0-SNAPSHOT/version typejar/type /dependency /dependencies properties project.build.sourceEncodingUTF-8/project.build.sourceEncoding maven.compiler.source1.7/maven.compiler.source maven.compiler.target1.7/maven.compiler.target /properties /project - Note: cepdemopersistence-1.1-SNAPSHOT dependency is not used in any code - don't know how it got there!
