问题描述

使用：GG版本2.2.4;和Groovy / Grails工具套件版本：3.3.0.RELEASE



下面是一个问题：如何将特定的Grails JAR引入使用GGTS构建的WAR？



作为一个侧面的问题，为什么WAR没有把JAR打包进去呢？为什么grails run-app工作得很好，但是部署WAR（在开发或生产中）失败了？

这是背景：



当我在Windows 7 deveopement计算机上本地运行grails run-war时，它会失败： 

  2013-10-16 11：36：05,371 [localhost-startStop-1]错误context.ContextLoader  - 上下文初始化失败

当我运行grails war，然后将Production WAR部署到我的服务器上的Tomcat 6时，我在catalina.out中得到了一个类似的部署错误：

我可以在WAR中探索，并看到WEB-INF / lib /不包含上述两个类所在的JAR（grails-plugin-testing-2.2.4.jar）。

我试过把

  grails.war.dependencies = [
grails-plugin-testing-2.2.4 .jar

转换为config.groovy，但这并不起作用。 WAR仍然没有包含那个JAR，并且我得到了同样的错误。

因此，我只是将grails-plugin-testing-2.2.4.jar放入了WEB- INF / lib文件夹并重新部署并验证上述错误消失，但现在我在服务器上发现另一个错误：

我将调查第二个错误，并在另一个问题中询问它并在这里引用它。 [更新：如果我还将grails-test-2.2.4.jar放入服务器上的WEB-INF / lib中，则此错误消失。然后，WAR部署并成功运行。]



要保留这个问题并回答一个主题，我如何将这2个JAR放入WAR中？不过，当然，也许有一个解决方案可以解决这两个问题（他 - 他 - 他 - 不太可能，但值得一提！）例如，我是无知的至于为什么使用grails-plugin-testing-2.2.4.jar。也许有一个设置需要改变，让它消失。



感谢！

解决方案

好的 - 想出来 - 足以让它工作....



[仍然诅咒为什么GG没有选择为了找出哪些JAR文件包含在WAR部署过程中报告丢失的类，我只是做了一个狩猎并啄食了这些JAR文件。 dist文件夹包含安装了Groovy / Grails v2.2.4的Grails JAR（C：\grails-2.2.4\dist）。我用7zip来浏览JAR。由于两个班都在其中有测试一词，因此我首先在名称中使用测试的JARS中查找并轻松找到它们。这就是我弄清楚上面列出的包含这些类的问题的两个JAR文件。



将它们放在服务器上的WEB-INF / lib文件夹中，那么成功启动/部署项目证实，让他们在WAR中可以解决问题。



为了让他们进入项目并在WAR创建时进入WAR ，我做到了这一点...... 

  1）对所涉及的项目运行grails clean
 2）close项目（和所有其他项目）
 3）退出g& g工具套件
 4）使用Windows资源管理器将jar文件拖到项目的PROJECTNAME / lib目录中。 
 5）启动g& g工具套件
 6）打开项目
 7）右键单击Project Name并选择Groovy Tools  - >刷新依赖关系

现在，也许您不必跳过所有这些循环来获取Refresh Dependencies工作，但这就是我所做的。如果我只是做＃7，而不先做其他的东西，它不适用于这个版本的GGTS。现在，WAR会在服务器上正确生成并部署。


Using: GG ver 2.2.4; and Groovy/Grails Tool Suite Version: 3.3.0.RELEASE

Here's the question: How do I get a specific Grails JAR into the WAR built with GGTS?

As side questions, why doesn't the WAR get that JAR packaged into it? And why does "grails run-app" work just fine, but deploying the WAR (in Development or Production) fails?

Here's the background:

When I run "grails run-war" locally on my Windows 7 deveopement computer, it fails with:

2013-10-16 11:36:05,371 [localhost-startStop-1] ERROR context.ContextLoader  - Context initialization failed

**Caused by: java.lang.NoClassDefFoundError: grails/test/mixin/domain/DomainClassUnitTestMixin**

When I run "grails war" and then deploy the Production WAR to Tomcat 6 on my server, I get a similar deployment error inside catalina.out:

I can explore inside the WAR, and see that WEB-INF/lib/ does NOT contain the JAR in which both of the above classes reside (grails-plugin-testing-2.2.4.jar).

I tried putting 

grails.war.dependencies = [
    "grails-plugin-testing-2.2.4.jar"
    ]

into config.groovy and this did not work. The WAR still did not contain that JAR and I got the same error.

So, I just put grails-plugin-testing-2.2.4.jar into the WEB-INF/lib folder on the server and re-deployed and verified that the error above goes away, but now I get another error on the server:

I'll investigate the second error and ask about it in a different question and reference it here. [UPDATE: This error goes away if I also put grails-test-2.2.4.jar into WEB-INF/lib on the server. Then, the WAR deploys and runs successfully.]

To keep this Question/Answer to one topic, how do I get these 2 JARs into the WAR?

But, of course, perhaps there is ONE solution that would solve BOTH issues (he-he-he - not likely but worth mentioning!) For example, I am ignorant as to why grails-plugin-testing-2.2.4.jar is used. Perhaps there is a setting I need to change to have that "go away."

THANKS!

解决方案

OK - figured it out - enough to make it work....

[Still bamboozled as to why GG didn't pick up those JARs all on its own.]

To figure out which JAR files contained the classes that were reported missing during WAR deployment, I just did a hunt and peck in the dist folder containing grails JARs where Groovy/Grails v2.2.4 was installed (C:\grails-2.2.4\dist). I used 7zip to just browse the JARs. Since both classes had the word "test" in them, I looked first in JARS with "test" in the name and found them easily. That's how I figured out the two JAR files that I listed above in the question that contained those classes.

Putting them in the WEB-INF/lib folder on the server and then having a successful start/deployment of the project confirmed that having them in the WAR would fix the issue.

To get them into the Project and thus the WAR when it's created, I did this...

1) run "grails clean" on the project in question
2) close the project (and all others)
3) exit g&g tool suite
4) drag the jar file to your "PROJECTNAME/lib" directory for your project using Windows Explorer.
5) start g&g tool suite
6) open the project
7) right-click on the Project Name and choose Groovy Tools -> Refresh Dependencies

Now, maybe you don't have to jump thru ALL those hoops to get Refresh Dependencies to work, but that's what I did. If I JUST do #7, without doing the other stuff first, it does not work on this version of GGTS. Now, the WAR generates and deploys correctly on the server.

这篇关于WAR部署中的Groovy Grails工具套件NoClassDefFoundError的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
