并将maven生成源文件夹作为eclipse源文件夹 [英] M2E and having maven generated source folders as eclipse source folders
问题描述
为了让eclipse看到这个生成的代码,我需要添加target / generated-sources / apt作为eclipse项目的源文件夹。
但是,这会导致类型Maven配置问题的错误说
项目配置不是最新的pom.xml。运行项目
配置更新
我想我知道为什么会这样,因为eclipse有一组不同的源文件夹maven的集合但是我需要这个不同的集合,因为我需要eclipse才能看到生成的源文件夹...
当构建纯Maven时,这些源文件夹将包括在构建中,由maven。
btw,我已经升级到官方eclipse版本的maven eclipse插件,m2e 1.0 - 以前是什么m2eclipse。我想看看是否可以找到一个解决方案/解决方案与m2e插件,我必须回到旧的m2eclipse版本。
您需要使用构建助手来附加源目录-plugin 。
像这样:
< plugin>
< groupId> org.codehaus.mojo< / groupId>
< artifactId> build-helper-maven-plugin< / artifactId>
<执行>
< execution>
< id> add-source< / id>
< phase> generate-sources< / phase>
< goals>
< goal> add-source< / goal>
< / goals>
< configuration>
< sources>
< source> $ {project.build.directory} / generated-sources / java /< / source>
< / sources>
< / configuration>
< / execution>
< / executions>
< / plugin>
您还需要:
- 从Eclipse Marketplace安装Apt M2E Connector。
要执行此操作,请单击pom.xml的概述选项卡中的错误,然后选择发现。 - 确保build-helper-maven-plugin没有插件执行过滤器(请参阅 http://wiki.eclipse.org/M2E_plugin_execution_not_covered )
I have a maven project in eclipse and have maven goals that run annotation processors to generate code. The output folder for this code is target/generated-sources/apt.
In order for eclipse to see this generated code I need to add target/generated-sources/apt as a source folder to the eclipse project.
However, this causes there to be an error of type "Maven Configuration Problem" saying
Project configuration is not up-to-date with pom.xml. Run project configuration update
I think I understand why this is the case as eclipse has a different set of source folders to maven's set. But I need this different set, as I need eclipse to be able to see the generated source folders...
When doing a pure maven built, these source folders will be included in the build, by maven.
btw, I have upgraded to the official eclipse release of the maven eclipse plugin, m2e 1.0 - what used to be m2eclipse. I'd like to see if I can find a work around/solution to this with the m2e plugin before I have to go back to the old m2eclipse version.
You need to attach the source directory with the build-helper-plugin.
Like so:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>${project.build.directory}/generated-sources/java/</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
You will also need to:
- Install the "Apt M2E Connector" from the Eclipse Marketplace. To do so click the error in the Overview tab of your pom.xml and select "Discover".
- Ensure there are no plugin execution filters for the build-helper-maven-plugin (see http://wiki.eclipse.org/M2E_plugin_execution_not_covered)
