如何从GWT SDK执行类路径中删除条目

标签： maven gwt migration classpath

我正在尝试将我的应用程序从2.6.1升级到2.7并且我正在执行以下异常执行目标org.codehaus.mojo：gwt-maven-plugin：2.7.0：在我的项目上编译（默认）：< / p> 

[INFO] Compiling module cern.edms.ui.Application
[INFO] [ERROR] Unexpected internal compiler error
[INFO] java.lang.IllegalArgumentException
[INFO]  at org.objectweb.asm.ClassVisitor.<init>(Unknown Source)
[INFO]  at org.objectweb.asm.ClassVisitor.<init>(Unknown Source)
[INFO]  at com.google.gwt.dev.javac.BytecodeSignatureMaker$CompileDependencyVisitor.<init>(BytecodeSignatureMaker.java:59)
[INFO]  at com.google.gwt.dev.javac.BytecodeSignatureMaker.visitCompileDependenciesInBytecode(BytecodeSignatureMaker.java:227)

我发现信息可能是因为我的类路径中的ASM版本错误（Strange error during running GWT 2.7 in DevMode），因此我检查了它。实际上在我的classpath中有两个版本的ASM：4.2和5.0.3。这是因为其中一个依赖项依赖于依赖于ASM 4.2的cglib。 GWT依赖于ASM 5.0.3。

这是我的完整类路径：

如何从类路径中排除4.2版中的ASM？

理想情况下，您只需将项目拆分为单独的客户端和服务器代码模块，这样就可以避免像这样的类路径冲突。您可以从这些原型中汲取灵感：https://github.com/tbroyer/gwt-maven-archetypes

但是，鉴于ASM 4+保证了向后兼容性，您也可以使用ASM 5代替ASM 4：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.ow2.asm</groupId>
            <artifactId>asm-parent</artifactId>
            <version>5.0.3</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

我终于通过在cglib依赖项中排除ASM来设法构建项目。这是我的代码：

<dependency>
  <groupId>cglib</groupId>
  <artifactId>cglib</artifactId>
  <version>3.1</version>
  <exclusions>
    <exclusion>
      <groupId>org.ow2.asm</groupId>
      <artifactId>asm</artifactId>
    </exclusion>
  </exclusions>
</dependency>

假设gwt-maven-plugin文档，您可以设置runClasspathExclude属性，以便在运行dev模式时从classPath中排除jars（并且仅在DEV模式下）：

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>gwt-maven-plugin</artifactId>
            <configuration>
                <runClasspathExcludes>
                    <runClasspathExclude>jetty-webapp-9.2.4.v20141103.jar</runClasspathExclude>
                    <runClasspathExclude>jetty-xml-9.2.4.v20141103.jar</runClasspathExclude>
                    <runClasspathExclude>jetty-util-9.2.4.v20141103.jar</runClasspathExclude>
                    <runClasspathExclude>jetty-servlet-9.2.4.v20141103.jar</runClasspathExclude>
                    <runClasspathExclude>jetty-security-9.2.4.v20141103.jar</runClasspathExclude>
                </runClasspathExcludes>
            </configuration>
        </plugin>

请注意，此配置由＆＃34;运行＆＃34;仅限目标：mvn gwt：run
