你好，当我在网络bean中运行我的程序是工作，但当我构建这个并在cmd中运行（java -jar name.jar）我有这个错误 - ＆gt; http://scr.hu/1det/p8tow 我使用maven这是我的pom.xml-＆gt;＆gt;

但是当我在没有maven的情况下制作项目并添加库时，它不起作用，我得到了同样的错误

我是第二个安德烈亚斯的评论。

IDE或IDE的Maven插件，可以很好地在后台维护类路径。这是Eclipse中Maven项目的.classpath文件的内容，例如：

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" output="target/classes" path="src/main/java">
        <attributes>
            <attribute name="optional" value="true"/>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="src" output="target/test-classes" path="src/test/java">
        <attributes>
            <attribute name="optional" value="true"/>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry excluding="**" kind="src" output="target/test-classes" path="src/test/resources">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
    <classpathentry kind="output" path="target/classes"/>
</classpath>

如果您在IDE之外工作，则必须自己处理依赖关系。

为什么当我开始计划不工作但在netbeans工作？
