与清单相关的java问题。罐装MF

Question

我已经在/usr/local/bin/niidle文件夹中创建了jar。罐子

我已经把舱单贴好了。罐中的MF如下所示：

Manifest-Version: 1.0
Main-Class: com.ensarm.niidle.web.scraper.NiidleScrapeManager
Class-Path: hector-0.6.0-17.jar

---

还有我的赫克托-0.6.0-17。jar文件位于以下文件夹中：

/Projects/EnwelibDatedOct13/Niidle/lib/hector-0.6.0-17.jar

---

我加上了这个“赫克托-0.6.0-17”。在niidle的罐子里。jar文件夹如下：

niidle.jar/lib/hector-0.6.0-17.jar

---

当我用这个命令运行时：

java -jar /usr/local/bin/niidle.jar arguments....

---

然后我得到如下错误信息：

Exception in thread "main" java.lang.NoClassDefFoundError: me/prettyprint/hector/api/Serializer
    at com.ensarm.niidle.web.scraper.NiidleScrapeManager.main(NiidleScrapeManager.java:21)

当我再次使用不同的命令运行时，如下所示：

java -cp /Projects/EnwelibDatedOct13/Niidle/lib/hector-0.6.0-17.jar -jar /usr/local/bin/niidle.jar arguments..... 

-------然后我也收到了同样的错误信息：--

Exception in thread "main" java.lang.NoClassDefFoundError: me/prettyprint/hector/api/Serializer
    at com.ensarm.niidle.web.scraper.NiidleScrapeManager.main(NiidleScrapeManager.java:21)

那么告诉我解决方法是什么。或者舱单上的任何修改。罐装MF

Answer 1

java -cp /Projects/EnwelibDatedOct13/Niidle/lib/hector-0.6.0-17.jar -jar /usr/local/bin/niidle.jar arguments.....

不能同时使用-cp开关和-jar开关

从http://mindprod.com/jgloss/classpath.html

If you use the -jar option, java.exe ignores the classpath. It will only look in that jar!! Try using the manifest Class-Path instead to get Java to look in auxiliary jars

---

And I have added this 'hector-0.6.0-17.jar' in niidle.jar folder as follows:

据我所知，你不能用这种方式嵌套.jar文件

既然你有Class-Path: hector-0.6.0-17.jar，你就需要把needle.jar和hector-0.6.0-17.jar并排，从它们的公共目录运行niidle.jar（如果你愿意，可以使用-jar开关）
