`/usr/bin/buildclasspath`执行`/usr/bin/groovy时的消息`

您希望我向您介绍哪个“Java扩展”？“一些特定的罐子”？我没有具体说明。我真的很喜欢这些毫无意义的信息

更新1： 两者：

# groovy --version
/usr/bin/build-classpath: Could not find /lib/jvm/java Java extension for this JVM
/usr/bin/build-classpath: error: Some specified jars were not found
Groovy Version: 1.8.9 JVM: 1.7.0_79 Vendor: Oracle Corporation OS: Linux

# java -version
java version "1.7.0_79"
OpenJDK Runtime Environment (fedora-2.5.5.0.fc20-x86_64 u79-b14)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

如中所述，没有任何帮助

对于这两个

，都有一个程序提供“java[c]”

，它是OpenJDK

也没用

更新2： 我安装并设置为备选方案：

# alternatives --config java
# alternatives --config javac

无济于事

更新3： 第一条消息来自

/usr/share/javautils/java函数：

# java -version
java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

看起来你的Java安装搞砸了。建议使用替代工具进行配置，以仅选择OpenJDK。此stackoverflow问题中指出了解决此问题的进一步尝试。但这似乎归结为不安装OracleJDK

根据评论，如果这些链接没有帮助，我会在我的答案中添加这个变通方法：即从解包下载zip，将JAVA_HOME设置为正确的JDK目录，并使用其中的shell脚本。页面上还对GVM进行了描述，与纯zip相比，使用GVM安装Groovy要舒服一些。尽管如此，这还是绕开了Fedora上的正确安装，因此只有在没有其他功能的情况下，或者如果您只想在本地安装，才应该使用它

卸载FC的Groovy并遵循（非常感谢！）上的说明完成了以下任务：

因此，可能不是您的java，而是您的groovy安装出了问题。我只能建议一种解决方法，那就是使用来自的zip分发版，并改用它。由于Java正在工作，您可能必须将Java_设置为HOME，否则您应该能够直接从该zip使用groovy。我一开始并没有建议这样做，因为您尝试了系统变量和包管理器。但是，由于这些事情失败得如此严重…非常感谢链接！如果你回答我，我就接受。如果不是，我会接受我自己的。
