Grails 1.4.0.M1（带STS 2.7.0.M2）GantBuilder的NoClassDefFoundError [英] Grails 1.4.0.M1 (with STS 2.7.0.M2) NoClassDefFoundError for GantBuilder

问题描述

我刚刚升级到...

• Grails 1.4.0.M1


• Groovy 1.8.0


• STS版本：2.7.0.M2 Build Id：201106101000 - 适用于Mac的64位Cocoa版本


• 我有OS X 10.5。 8。使用JVM 1.5.0

• Grails 1.4.0.M1
• Groovy 1.8.0
• STS Version: 2.7.0.M2 Build Id: 201106101000 - 64bit Cocoa version for Mac
• I have OS X 10.5.8. with JVM 1.5.0

当我在现有项目上运行grails命令，例如创建应用程序或升级时，我得到GantBuilder的以下NoClassDefFoundError。 （见下面的完整跟踪）

When I run a grails command eg 'create-app' or 'upgrade' on an existing project I get the following NoClassDefFoundError for the GantBuilder. (see below for full trace)

从这个论坛是gant_groovy1.8-1.9.5.jar丢失。我直接将它添加到项目中，并将其添加到一个groovy / lib文件夹（并且转到STS - >首选项 - > Groovy - >编译器 - >更新所有Groovy类路径容器），但是我仍然收到错误。 （当我将gant_groovy1.8-1.9.5.jar添加到groovy / lib时，它是一个单独的groovy下载，我不知道哪个groovy / lib文件夹STS用于内部grails shell命令或如何查看STS groovy类路径）

A proposed solution for a similar problem from this forum is that gant_groovy1.8-1.9.5.jar is missing. I've added this to the project directly and also to a groovy/lib folder (and gone to STS -> preferences -> Groovy -> compiler -> Update All Groovy Classpath Containers) but I still get the error. (When I added gant_groovy1.8-1.9.5.jar to groovy/lib it was to a separate groovy download, I'm not sure which groovy/lib folder STS uses for the internal grails shell commands or how to view the STS groovy class path)

有没有人有任何想法？

推荐答案

如果我明白是对的，Grails不要在你的groovy / lib文件夹中使用jar，而是在Grails安装文件夹中使用jar。你可能想试试这个：

If what I understand is right, Grails don't use the jar in your groovy/lib folder, but the jar in the Grails Installation folder. You may want to try this:

根据帖子这里，你应该去安装的Grails文件夹（％GRAILS_HOME％）。在该文件夹中，找到lib文件夹，并指定您拥有的gant_groovy.jar的正确版本。然后将％GRAILS_HOME％/ bin / startGrails.bat编辑为文本并添加以下行：

According to the post here, you should go to the Installed Grails Folder (%GRAILS_HOME%). In that folder, find the lib folder, and specify the right version of gant_groovy.jar that you have. Then edit the %GRAILS_HOME%/bin/startGrails.bat as text and add this line:

( set STARTER_CLASSPATH=%GRAILS_HOME%\lib\org.codehaus.groovy\groovy-all\jars\groovy-all-1.8.0.jar;%GRAILS_HOME%\dist\grails-bootstrap-1.4.0.M1.jar;%GRAILS_HOME%\lib\org.codehaus.gant\gant_groovy1.8\jars\gant_groovy1.8-1.9.5.jar 
)

请注意，上面的路径不是很准确（每个发行版看起来都不一样）。您应该在％GRAILS_HOME％文件夹中找到所需的jar，并相应地更改路径。

Note that the path on the above line is not very accurate(it seems different for each distribution). You should find the required jar in the %GRAILS_HOME% folder and change the path accordingly.
