带有Krasa插件的XJC

Question

你好，当我执行下面的ant-script时，我得到了一个构建错误。有人能帮我解决这个问题吗？

ANT输出：

Buildfile: D:\workspace\Webformular2\WebContent\WEB-INF\XSD-Pfad.ant 

[delete] Deleting directory D:\workspace\Webformular2\WebContent\WEB-INF\src 
[mkdir] Created dir: D:\workspace\Webformular2\WebContent\WEB-INF\src xjc: 
[xjc] Consider using <depends>/<produces> so that XJC won't do unnecessary compilation
[xjc] Compiling file:/D:/workspace/Webformular2/WebCo ntent/WEB-INF/jaxb/antragsdaten.xsd and others

BUILD FAILED D:\workspace\Webformular2\WebContent\WEB-INF\XSD-Pfad.ant:11: java.lang.NoClassDefFoundError: javax/validation/constraints/NotNull

Ant脚本

<project default="xjc">
        <delete dir="src"/>
        <mkdir dir="src" />
        <target name="xjc" description="JAXB Generation">

                    <fileset dir="lib" includes="*.jar" />
                  </classpath>
                </taskdef>`
`

                </xjc>
        </target>
</project>`

Answer 1

- Ant-Skript - <project default="xjc"> <delete dir="src"/> <mkdir dir="src" /> <target name="xjc" description="JAXB Generation"> <taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask"> <classpath> <fileset dir="lib" includes="*.jar" /> </classpath> </taskdef> <xjc destdir="src" extension="true"> <schema dir="jaxb" includes="*.xsd"/> <arg line=" -XJsr303Annotations -XReplacePrimitives"/> </xjc> </target> </project>

Answer 2

您的lib目录中缺少"validation-api.jar“。
