如何将依赖关系复制到gae war / WEB-INF / lib [英] How to copy dependencies to gae war/WEB-INF/lib

问题描述

我来自Ant的角度，请原谅我。我意识到在这里已经有很多关于如何设置依赖关系的问题，但是他们都没有告诉如何去做需要做的事情。

问题1 ：
目前，在使用maven-war-plugin时，当我运行mvn war：war时，它会在目标文件夹中创建一个war文件夹。

$ b $但是，我希望将所有依赖项的jar复制到由google eclipse plugin（启用了gae，禁用gwt）设置的war / WEB-INF / lib中，而不会覆盖Google eclipse插件放置在那里的jar。

我不想设置war文件或war目录。我只需要将所有非gae jar文件复制/合并到gae jar文件中，这样当项目作为gae web应用程序运行时，Eclipse不会抱怨ClassNotFoundException。

问题2 ：
在Eclipse中使用Ant时，我可以在Eclipse中运行Ant目标。 b

现在，我必须从shell窗口执行mvn命令（这对于Eclipse会话的存在是相互忽略的）。看来只有当我更新依赖关系时，自动完成的唯一一件事情。

有没有办法，或者是任何用于eclipse的插件，它们可以让我在内部运行mvn目标Eclipse？

其他信息：
$ b mvn依赖项：copy-dependencies 会持续复制到 target / dependency 目录中，其中包含以下内容：

 < plugin> 
< artifactId> maven-dependency-plugin< / artifactId> 
<执行次数> 
<执行> 
< id>复制依赖关系< / id> 
<阶段>过程资源< /阶段> 
<目标> 
<目标>复制依赖关系< / goal> 
< /目标> 
<配置> 
< outputDirectory> $ {basedir} / war / WEB-INF / lib /< / outputDirectory> 
< overWriteReleases> false< / overWriteReleases> 
< overWriteSnapshots> false< / overWriteSnapshots> 
< overWriteIfNewer> true< / overWriteIfNewer> 
< excludeArtifactIds> gwt-user，gwt-dev< / excludeArtifactIds> 
< / configuration> 
< /执行> 
< /执行次数> 
< / plugin> 
  

我甚至尝试改变为绝对路径

 <输出目录> 
 / home / geek / eclipse / workspace / Demo-autoshoppe / holycow 
< / outputDirectory> 
  

但是holycow目录仍然是空的，mvn仍然存在于复制到 target /依赖项目录。我当前的解决方案是将 target / dependency 作为 war / WEB-INF / lib 的软链接，这是非常糟糕的杂牌。为什么maven对outputDirectory规范不敏感？我使用的是Ubuntu的Maven 2.2。

解决方案

我有真正的答案给你，我的男人。 b

使用default-cli执行ID。确保你使用的是Maven 2.2+。这个exec-id适用于mojo的命令行执行。

 < build> 
< pluginManagement> 
< plugins> 
 <！ - 将依赖关系复制到war / WEB-INF / lib以获得GAE proj合规性。 - > 
< plugin> 
< groupId> org.apache.maven.plugins< / groupId> 
< artifactId> maven-dependency-plugin< / artifactId> 
<执行次数> 
<执行> 
< id> default-cli< / id> 
<目标> 
<目标>复制依赖关系< / goal> 
< /目标> 
<配置> 
< outputDirectory> $ {basedir} / war / WEB-INF / lib /< / outputDirectory> 
< overWriteReleases> false< / overWriteReleases> 
< overWriteSnapshots> false< / overWriteSnapshots> 
< overWriteIfNewer> true< / overWriteIfNewer> 
< excludeArtifactIds> gwt-user，gwt-dev< / excludeArtifactIds> 
< / configuration> 
< /执行> 
< /执行次数> 
< / plugin> 
< / plugins> 
< / pluginManagement> 
< / build> 
  

干杯。

I'm coming from Ant perspective, so pardon me. I realise there are quite a few questions here already on how to maven dependencies, but none of them seem to tell how to do what need to do.

Question 1: Currently, in conjunction with using maven-war-plugin, when I run mvn war:war, it creates a war folder in target folder.

However, I wish copy all the dependencies' jars to war/WEB-INF/lib set up by google eclipse plugin (with gae enabled, gwt disabled), without overwriting the jars that google eclipse plugin placed there.

I don't wish to setup a war file or war directory. I just need to copy/consolidate all the non-gae jars with the gae jars so that when the project is run as a gae web app, Eclipse would not complain ClassNotFoundException.

Question 2: When using Ant in Eclipse, I could run Ant targets within Eclipse.

Right now, I have to perform mvn commands from a shell window (which is mutually oblivious to the existence of an Eclipse session). It appears that the only thing that is automatically done is whenever I update dependencies.

Is there a way, or any plugin for eclipse that would allow me to run mvn goals within Eclipse?

Additional info:

mvn dependency:copy-dependencies persists in copying to target/dependency directory, with the following:

  <plugin>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
      <execution>
        <id>copy-dependencies</id>
        <phase>process-resources</phase>
        <goals>
          <goal>copy-dependencies</goal>
        </goals>
        <configuration>
          <outputDirectory>${basedir}/war/WEB-INF/lib/</outputDirectory>
          <overWriteReleases>false</overWriteReleases>
          <overWriteSnapshots>false</overWriteSnapshots>
          <overWriteIfNewer>true</overWriteIfNewer>
          <excludeArtifactIds>gwt-user,gwt-dev</excludeArtifactIds>
        </configuration>
      </execution>
    </executions>
  </plugin>

I even tried changing to absolute path

<outputDirectory>
  /home/geek/eclipse/workspace/Demo-autoshoppe/holycow
</outputDirectory>

But holycow directory is still empty and mvn still persists in copying to target/dependency directory. My current solution is to softlink target/dependency as war/WEB-INF/lib, which is a very very bad kludge. Why is maven not sensitive to outputDirectory specification? I am using Ubuntu's maven 2.2.

解决方案

I have the real answer for you, my man.

Use the "default-cli" execution id. Make sure you're using Maven 2.2+. This exec-id applies to command-line executions of the mojo.

  <build>
    <pluginManagement>
      <plugins>
        <!-- Copy dependencies to war/WEB-INF/lib for GAE proj compliance. -->
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-dependency-plugin</artifactId>
          <executions>
            <execution>
              <id>default-cli</id>
              <goals>
                <goal>copy-dependencies</goal>
              </goals>
              <configuration>
                <outputDirectory>${basedir}/war/WEB-INF/lib/</outputDirectory>
                <overWriteReleases>false</overWriteReleases>
                <overWriteSnapshots>false</overWriteSnapshots>
                <overWriteIfNewer>true</overWriteIfNewer>
                <excludeArtifactIds>gwt-user,gwt-dev</excludeArtifactIds>
              </configuration>
            </execution>
          </executions>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>

Cheers.
