[英]NoClassDefFoundError when running an OSGI bundle as classic jar
I have common code between a Java application and an RCP application. 我在Java应用程序和RCP应用程序之间有共同的代码。 So I have created an OSGI bundle which contains:
所以我创建了一个OSGI包,其中包含:
I built all with Tycho Manifest-first and it worked fine until I needed to use an external jar in my common code. 我用Tycho Manifest-first构建了所有内容,并且它工作正常,直到我需要在我的公共代码中使用外部jar。
I need to use jsch so I have add jsch in my MANIFEST.MF : 我需要使用jsch所以我在我的MANIFEST.MF中添加了jsch:
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Main-Class: mygroupid.Main
Bundle-Name: Common tools
Bundle-SymbolicName: common-tools
Bundle-Version: 1.0.1.qualifier
Export-Package: mygroupid,
mygroupid.tools
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Import-Package: org.osgi.framework;version="1.3.0"
Require-Bundle: com.jcraft.jsch;bundle-version="0.1.46"
I build my RCP application with Tycho and it works. 我用Tycho构建我的RCP应用程序,它可以工作。 But when I run the bundle as pure JAR with
java -jar myjar.jar
, I get the following error: 但是当我使用
java -jar myjar.jar
将包作为纯JAR运行时,我收到以下错误:
Exception in thread "main" java.lang.NoClassDefFoundError: com/jcraft/jsch/JSchException
If I export my bundle with Eclipse, it works. 如果我用Eclipse导出我的包,它就可以了。 So I have an error in my tycho configuration...
所以我的tycho配置有错误...
How to solve this problem ? 如何解决这个问题呢 ? Is there a jar-with-dependencies for Tycho ?
对Tycho有依赖的jar吗? It seems not to be the case What I have missed ?
似乎不是这样的我错过了什么?
(My configuration: Eclipse Juno with m2e, Tycho 0.16.0, p2: Juno, Tycho: packaging>eclipse-plugin, target-platform-configuration : resolver=p2 and pomDependencies=consider.) (我的配置:带有m2e的Eclipse Juno,Tycho 0.16.0,p2:Juno,Tycho:打包> eclipse-plugin,target-platform-configuration:resolver = p2和pomDependencies =考虑。)
Just add the maven-assembly-plugin to your build, and let it build a jar with all dependencies: 只需将maven-assembly-plugin添加到您的构建中,然后让它构建一个包含所有依赖项的jar:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
Alternatively, you can also create an assembly where the jars are packed individually . 或者,您也可以创建一个装配,其中罐子是单独包装的 。 You'll need to write your own assembly descriptor for this.
您需要为此编写自己的程序集描述符 。
if you are working on Linux/Unix platform, you can try java -classpath :myjar.jar com.yourpackage.mainclass 如果你在Linux / Unix平台上工作,你可以试试java -classpath:myjar.jar com.yourpackage.mainclass
if you are workin on windows platform, you can try java -classpath ;myjar.jar com.yourpackage.mainclass 如果您在Windows平台上工作,可以尝试java -classpath; myjar.jar com.yourpackage.mainclass
