在DevSever目标运行期间Appengine模块Maven错误 [英] Appengine Modules Maven Error during DevSever Goal Run

问题描述

我一直在尝试使用模块支持来运行一个新项目，但随时都会出现跟随错误，无法调试它，

com。 google.apphosting.utils.config.EarHelper reportConfigException
[INFO]信息：应用程序目录'path-to-project / DemoEar-1.0.0-SNAPSHOT / DemoWarApp'必须存在并且是目录。

我的模块结构在

主application.xml中包含

 < module> 
< web> 
< web-uri> DemoWarApp< / web-uri> 
< context-root> DemoWarApp< / context-root> 
< / web> 
< / module> 
  

显然没有指向正确的war文件夹路径。没有人知道如何解决它？

谢谢

创建的bundle文件夹必须与application.xml中的 web-uri 匹配。因此，您可以在 maven-ear-plugin

$ b中用 bundleFileName 更改包文件夹名称
$ b

 < modules> 
< webModule> 
< groupId> groupId-of-DemoWarApp< / groupId> 
< artifactId> artifactId-of-DemoWarApp< / artifactId> 
< bundleFileName> DemoWarApp< / bundleFileName> 
< / webModule> 
< / modules> 
  

或者您将 web-uri 更改为{module-name} - {version}每次匹配创建的包文件夹名称。

我会推荐一个独立于版本的bundle bundleFileName （与 web-uri 相同），所以当版本发生变化时，不必担心它。

完整的ear插件片段：

 < plugin> 
< groupId> org.apache.maven.plugins< / groupId> 
< artifactId> maven-ear-plugin< / artifactId> 
< version> 2.9< / version> 
<配置> 
<模块> 
< webModule> 
< groupId> groupId-of-DemoWarApp< / groupId> 
< artifactId> artifactId-of-DemoWarApp< / artifactId> 
< bundleFileName> DemoWarApp< / bundleFileName> 
< / webModule> 
< / modules> 
< version> 5< / version> 
< defaultLibBundleDir> lib< / defaultLibBundleDir> 
< unpackTypes> war< / unpackTypes> 
< / configuration> 
< / plugin> 
  

i have been trying to run a new project with modules support, but am getting following error all the time, unable to debug it,

com.google.apphosting.utils.config.EarHelper reportConfigException [INFO] INFO: Application directory 'path-to-project/DemoEar-1.0.0-SNAPSHOT/DemoWarApp' must exist and be a directory.

my module structure is below

main application.xml contains

 <module>
 <web>
 <web-uri>DemoWarApp</web-uri>
 <context-root>DemoWarApp</context-root>
</web>
</module>

its clearly not pointing to the proper war folder path. does anyone know how to fix it?

Thanks

解决方案

The bundle folder that is created must match the web-uri in your application.xml. So, you either change the bundle folder name with bundleFileName in the maven-ear-plugin

<modules>
        <webModule>
            <groupId>groupId-of-DemoWarApp</groupId>
            <artifactId>artifactId-of-DemoWarApp</artifactId>
            <bundleFileName>DemoWarApp</bundleFileName>
        </webModule>
</modules>

or you change the web-uri to {module-name}-{version} every time to match the created bundle folder name.

I would recommend a version independent bundle bundleFileName (that is the same as your web-uri) so you don't have to bother with it when the version changes.

Complete ear plugin snippet:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-ear-plugin</artifactId>
    <version>2.9</version>
    <configuration>
      <modules>
        <webModule>
            <groupId>groupId-of-DemoWarApp</groupId>
            <artifactId>artifactId-of-DemoWarApp</artifactId>
            <bundleFileName>DemoWarApp</bundleFileName>
        </webModule>
      </modules>
      <version>5</version>
      <defaultLibBundleDir>lib</defaultLibBundleDir>
      <unpackTypes>war</unpackTypes>
    </configuration>
</plugin>
