src/main/webapp directory not recognized by Eclipse

由 心不动则不痛 提交于 2019-12-04 09:17:55
问题 I use m2eclipse to import Maven Java projects in Eclipse. It fails to recognize src/main/webapp as a source directory. Graphically in the package explorer (or when I look into Java-Build-Path in the project's properties), this directory isn't in the list of sources folder (while src/main/java or src/main/resources do). To access it, I have to look directly into the src/ directory, and start unfolding... Not very convenient! However, if I run maven install , the resources are copied to the

Maven: Extract dependency resources before test

由 风流意气都作罢 提交于 2019-12-04 08:36:40
I have a multimodule Maven project. One subproject hosts XSL/XML resource files. The other project hosts Java code that needs to use these files in its unit tests. In the dependency's jar, the resources lie in the folder xml-resources . I found this example and tried to change it for my needs: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.4</version> <executions> <execution> <id>resource-dependencies</id> <phase>process-test-resources</phase> <goals> <goal>unpack-dependencies</goal> </goals> <configuration> <classifier>xml

Inter Project Dependencies in Maven

由 无人久伴 提交于 2019-12-04 08:22:00
I have two maven projects: project-api project-impl project-impl's POM specifies a dependency on project-api. The top level aggregation pom lists modules project-api and project-impl. If I run compile at top level, the dependencies resolves correctly. If I run compile at project-impl, then it can't find dependency project-api. How can I set up maven such that when project-impl compiles, it first compiles and collects its dependencies on other projects? you can only do that from the root project mvn -pl child -am this will build your sub project and also all dependencies in the same tree. in

How can I display a message in Maven

由 ☆樱花仙子☆ 提交于 2019-12-04 07:59:47
问题 How can I display a message in Maven? In ant, we do have "echo" to display a message, but in maven, how can I do that? 回答1: You can use the antrun plugin: <plugin> <artifactId>maven-antrun-plugin</artifactId> <executions> <execution> <phase>generate-resources</phase> <goals> <goal>run</goal> </goals> <configuration> <tasks> <echo>Hello world!</echo> </tasks> </configuration> </execution> </executions> </plugin> One issue though is that you have to choose what phase of the build lifecycle to
