jaxws_asm/package-info : 不支持的 major.minor 版本 0.0

Question

我有 Maven 项目，我正在使用 (wildfly-8.1.0.Final)，此外还使用 (jdk1.7.0_67)。获得我的项目 WAR 后，我尝试运行服务器，但总是有以下内容：

有什么帮助吗？！

Answer 1

我已经设法解决了这个问题。在我的 pom.xml 中，我只是替换了这个依赖项

<dependency>
     <groupId>org.apache.cxf</groupId>
     <artifactId>cxf-bundle</artifactId>
     <version>2.2.9</version>
</dependency>

有了这个

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-bundle-jaxrs</artifactId>
    <version>2.7.0</version>
</dependency>

Answer 2

我也遇到了同样的问题，Wildfly 自带了自己的 asm 库，所以如果您的代码有任何依赖于 asm 的依赖项，那么您的部署就是将 asm.jar 打包到您的 ear/jar 中，并且当您将它们部署到Wildfly ...冲突和问题。

如果你需要包含依赖于asm的依赖，只需包含它但排除asm，如：

<dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy</artifactId>
    <version>${groovy.version}</version>
    <exclusions>
        <exclusion>
            <artifactId>asm</artifactId>
            <groupId>asm</groupId>
        </exclusion>
        <exclusion>
            <artifactId>asm-util</artifactId>
            <groupId>asm</groupId>
        </exclusion>
        <exclusion>
            <artifactId>asm-analysis</artifactId>
            <groupId>asm</groupId>
        </exclusion>
        <exclusion>
            <artifactId>asm-tree</artifactId>
            <groupId>asm</groupId>
        </exclusion>
    </exclusions>
</dependency>

那是我的问题，我在我的实用程序模块中使用了 groovy 依赖项和我的 EJB 中的实用程序.jar，所以当我调用部署在 wildfly10 中的 EJB（Web 服务使用者）时……Boooom 我得到了标题错误。

排除 asm 依赖后，一切正常。

注意：使用“mvn dependency:tree”来寻找包含 asm 作为依赖的包
