问题 I'm having a weird configuration problem with Maven in Eclipse. Although I can build the project and deploy it to tomcat without any errors, The Marker tab keeps showing the following message: [-] Maven Java EE Configuration Problem (x) JavaServer Faces 1.2 can not be installed : One or more constraints have not been satisfied. (x) JavaServer Faces 1.2 requires Dynamic Web Module 2.5 or newer. I am in fact using Dynamic Web Module 2.4, which would be the source of the message. I would need to

问题 For my team, I'd like to configure maven/eclipse build to automatically generate Java code from *.proto files (in a project that uses gRPC). Currently one needs to run mvn generate-source or mvn protobuf:compile (as in plugin usage page). Or what is the same add Run configuration to invoke maven goal compile . Whenever Eclipse Maven project is refreshed ( Alt + F5 ) or IDE is restarted, project is rebuilt but without what should appear in target/generated , thus turning project into red. So

问题 I'm sorry if I am asking a possibly-trivial question, but I am having so much trouble finding out exactly what Resolve Workspace Artifacts does in the Maven build window in the Eclipse IDE, using the M2Eclipse plugin. I'm referring to this: Does anyone have any idea? I tried google-ing and stackoverflow-ing the solution; there are lots of bug requests/reports but no clear-cut descriptions of this option. Thanks for the help. 回答1: Assume you have two or more projects in your workspace e.g.

问题 I am trying to use the maven-warpath-plugin available here. But I keep getting an error in my pom.xml file that says: Plugin execution not covered by lifecycle configuration: org.appfuse.plugins:maven-warpath-plugin:2.1.0:add-classes (execution: default, phase: generate-sources) How do I resolve this? Here is my pom.xml snippet for the plugin: <plugin> <groupId>org.appfuse.plugins</groupId> <artifactId>maven-warpath-plugin</artifactId> <version>2.1.0</version> <extensions>true</extensions>

问题 I am starting to configure my development environment and I am using Spring Tool Suite 2.8.1 along with m2E 1.01. As far as I can tell, since this is a Maven Project (my first), my Maven POM is dictating (along with m2E smarts) my project build configuration and dependencies. What I would like to know is why my IDE is displaying Java Build Problems that read "Archive required for library library/path/somejar.jar cannot be read or is not a valid zip file" when I can see the jars in my .m2

问题 I have a maven project. As activeByDefault I have the production profile. It seems I can't find a way to run it as application in Eclipse using the staging profile unless I put the activeByDefault in the staging profile. Is there a way to configure this so I don't have to edit the pom every time? 回答1: The only thing is affected in running Java app from Maven project in Eclipse is how application classpath is constructed. Generally in Maven there are several different classpaths scopes:

问题 I am trying to create a JAX-RPC webservice client using maven-jaxrpc-plugin in Eclipse using M2E. Here is the corresponding snippet from pom.xml <pluginManagement> <plugins> <plugin> <groupId>net.sf.jaxrpc-maven</groupId> <artifactId>maven-jaxrpc-plugin</artifactId> <version>0.3</version> <executions> <execution> <id>jax-rpc-scoring-client</id> <phase>install</phase> <goals> <goal>wscompile</goal> </goals> </execution> </executions> <configuration> <config>${project.basedir}/config.xml<

问题 I am trying to get ready for deployment and therefore I want to copy the correct configuration files to WEB-INF/classes/ before everything gets packed into the WAR file for either deployment or development . In the end I want to execute deployment-tasks whenever I call mvn glcoud:deploy - which is when I need deployment configuration files - and development-tasks whenever something else gets executed in my project directory. At the moment I have not decided how exactly I'm going to do it but

问题 I'm working with maven projects in Eclipse (Indigo). In order to compile some classes that need endorsed libraries (webservices-api.jar) I go to "Properties/Java Build Path/Order and Export" and move "Maven Dependecies" before "JRE System Library". The problem is that whenever I click on the "Maven/Update Project configuration" option the entries are rearranged and "JRE System Library" is always the first entry, and the code no longer compiles. Is there a way to have M2E remember my choice

问题 It took me a while to make this observation, but I see that m2e "magically" manages the classpath. Examples: If I Run as a Java application in the "src/java/main" source folder it excludes "test" scope. Note: The class was able to compile, but not able to run. But if I move that same class to the "src/java/test" folder then it is able to compile and run. If I Run as JUnit Test then the "test" scope is always included (even if the class is in the "main" source folder). The only way I made
