java Grails 2.0.4 错误打开 zip 文件或 JAR 清单缺少 Springloaded

Grails 2.0.4 Error opening zip file or JAR manifest missing Springloaded

提问by sim

I've just downloaded Grails 2.0.4 and extracted it to /opt/grails/grails-2.0.4/ and made sure that the GRAILS_HOME environment variable is correct. But whenever I try run the "grails" command, I get the following error:

我刚刚下载了 Grails 2.0.4 并将其解压缩到 /opt/grails/grails-2.0.4/ 并确保 GRAILS_HOME 环境变量是正确的。但是每当我尝试运行“grails”命令时，都会出现以下错误：

Error opening zip file or JAR manifest missing : /opt/grails/grails-2.0.4/lib/com.springsource.springloaded/springloaded-core/jars/springloaded-core-1.0.2.jar
Error occurred during initialization of VM
agent library failed to init: instrument

I don't understand what the problem could be. I've been using Grails-2.0.1 for months successfully in exactly the same way on exactly the same machine. I've tried re-downloading the grails-2.0.4.zip file in the hopes that it was a problem with the archive, but that didn't help. I also copied springloaded-core-1.0.2.jar from the grails-2.0.1/ directory, but that just caused another set of errors.

我不明白可能是什么问题。我已经在完全相同的机器上以完全相同的方式成功使用 Grails-2.0.1 几个月了。我尝试重新下载 grails-2.0.4.zip 文件，希望它是存档的问题，但这没有帮助。我还从 grails-2.0.1/ 目录中复制了 springloaded-core-1.0.2.jar，但这只会导致另一组错误。

Any idea what could be going wrong?

知道可能出了什么问题吗？

I experienced this error too. The problem is spaces in the grails home path.

我也遇到过这个错误。问题是 grails 主路径中的空间。

If it's this:

如果是这样：

c:/grails 2.1.0/grails2.1.0

Then it will give an error, as there's a space between "grails" and "2.1.0". I just removed the spaces and it started working.

然后它会给出一个错误，因为“grails”和“2.1.0”之间有一个空格。我刚刚删除了空格并开始工作。

It looks like your PATH has not been updated correctly. In other words, you are running the 2.0.1 grails script with GRAILS_HOME set to 2.0.4. You can tell because the version of spring loaded reported in the error message - 1.0.2 - is not the one required by Grails 2.0.4 (to help others diagnose this issue).

看起来您的 PATH 没有正确更新。换句话说，您正在运行 2.0.1 grails 脚本并将 GRAILS_HOME 设置为 2.0.4。您可以判断，因为错误消息中报告的 spring 加载版本 - 1.0.2 - 不是 Grails 2.0.4 所需的版本（帮助其他人诊断此问题）。

Have you cleared out the .grailsfolder in your home directory?

您是否清除了主目录中的.grails文件夹？

Grails caches a bunch of files in there, it could be that that is tripping you up.

Grails 在那里缓存了一堆文件，这可能会让您感到困惑。

I have had similar problems in the past when my internet connection wasn't a 100% reliable, it seems that the Grails downloader does not do thorough checking of downloaded files, so files in cache can become corrupt.

过去，当我的互联网连接不是 100% 可靠时，我遇到过类似的问题，Grails 下载器似乎没有对下载的文件进行彻底检查，因此缓存中的文件可能会损坏。

It's the folder hierarchy problem!

这是文件夹层次结构问题！

I have faced the same issue : when i set Grails_home make sure the path you are giving is e.g c:/grails2.1.0and not c:/grails2.1.0/grails2.1.0

我遇到了同样的问题：当我设置 Grails_home 时，请确保您提供的路径是 egc:/grails2.1.0而不是c:/grails2.1.0/grails2.1.0

it often happens when you unzip the folder 2 folder with same name are created one inside another.

当您解压缩文件夹 2 具有相同名称的文件夹时，经常会发生这种情况。

hope this will resolve!!!

希望这会解决！！！
