执行 org.codehaus.gmaven:gmaven-plugin:1.3:testCompile:groovy/lang/Closure 时缺少必需的类答案

【问题标题】：A required class was missing while executing org.codehaus.gmaven:gmaven-plugin:1.3:testCompile: groovy/lang/Closure执行 org.codehaus.gmaven:gmaven-plugin:1.3:testCompile:groovy/lang/Closure 时缺少必需的类

【问题描述】：

我正在尝试 mvn clean install 一个已登陆我的盘子的 maven 项目，但是我遇到了一个异常，我认为这可能是由于 Groovy 的版本冲突，这就是我得到的：

Failed to execute goal org.codehaus.gmaven:gmaven-plugin:1.3:testCompile (default) on project maven-myproject-plugin: Execution default of goal org.codehaus.gmaven:gmaven-plugin:1.3:testCompile failed: A required class was missing while executing org.codehaus.gmaven:gmaven-plugin:1.3:testCompile: groovy/lang/Closure

使用-e 标志进行跟踪：

            </dependencies>
        </plugin>

我已经尝试更新 groovy-all 和 gmaven-plugin 的版本，并且我还尝试按照 previous SO question 中的建议设置 providerSelection

这是我的 Java/Maven 版本：

mvn -version
Apache Maven 3.0.4 (r1232337; 2012-01-17 08:44:56+0000)
Maven home: /Users/JElsey/Development/tools/apache-maven-3.0.4
Java version: 1.6.0_32, vendor: Apple Inc.
Java home: /Library/Java/JavaVirtualMachines/1.6.0_32-b05-420.jdk/Contents/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x", version: "10.7.4", arch: "x86_64", family: "mac"

有什么可能导致这种情况的指针吗？

编辑 1：

我已尝试将 maven 降级到 2.2.1，并重新指向符号链接以确保它不会尝试使用 Apple 喜欢随附的预打包 3.0.4，如 here 所述。

我还是过不去，我不知道...

【解决方案1】：

我没有看到您遇到的确切错误，但我发现 Groovy 1.8.7、gmaven-plugin 1.4 和 gmaven-runtime-1.8 是一个成功的组合。请注意，我必须在 mvn groovy:shell 中包含 jansi 作为 this bug 的解决方法。

将 Groovy 1.8.7 添加到您的依赖项中：

<dependencies>
    <dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy-all</artifactId>
    <version>1.8.7</version>
</dependency>

然后添加插件配置：

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.gmaven</groupId>
            <artifactId>gmaven-plugin</artifactId>
            <version>1.4</version>
            <executions>
                <execution>
                    <goals>
                        <goal>generateStubs</goal>
                        <goal>compile</goal>
                        <goal>generateTestStubs</goal>
                        <goal>testCompile</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <providerSelection>1.8</providerSelection>
            </configuration>
            <dependencies>
                <dependency>

对于较新版本的 Groovy 和其他版本，也可以试试这个：

【讨论】：

GMaven 不应该用于编译高于 2.0.x 的 Groovy 版本。我上次更新 GMaven 是针对 2.0.1 编译 2.0 提供程序。 GMaven 有一些功能根本不起作用（比如特征）。我无耻地推荐GMavenPlus，但你也可以考虑Groovy-Eclipse。
