我对GraalVM很陌生,我正在努力塑造一个原生形象。
我正在一些官方教程上构建一个简单的示例。我仍然收到一个找不到主类的错误。这是我的pom。我错过了什么?每个设置都到位了。我有一个简单的Rest Controller,带有一个“hello”GetMap。独立的应用程序运行良好。它没有什么特别的,所以我不会发布代码,因为它毫无用处。只有在主类中,我有proxyBeanmethod=false

已解决。您需要在maven buld('mvn清洁包-P之前实际运行
graal`) the `vcvars` command. Goes something like
>C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvars.bat
>mvn clean package -P graal
对于那些感兴趣的人,我在这里提供了一个配置文件,非常重要的是,spring boot maven插件要在本机image maven插件之后,以避免与boot repackagi冲突

我是编程新手,我非常喜欢它。我刚刚下载了Eclipse,我遇到了一个无法帮助我解决的错误。不幸的是,它是德语的,但意思是:“找不到主类”-“Fehler: Hauptcroasse konnte nicht gefunden oder geladen werden” 我知道它与“”有关。因为这对我来说是全新的,所以你能帮我会很酷。 下面的错误源代码;
该链接描述了工具的用法 https://github.com/oracle/graal/blob/master/substratevm/CONFIGURE.md 我无法在JDK11的Graalvm版本19.0.3.2中找到此工具 我在哪里可以得到这个工具?
问题内容: 我有一个由Eclipse生成的.jar,我无法在其他计算机(与Windows XP)上运行。出现“找不到主类。程序将退出”消息。那台计算机可以在Netbeans生成的另一个.jar上正常运行,所以我想JRE并不是问题。我更新了JRE,但没有改变。问题是什么? 更新:我忘了提,我做了一个可运行的jar文件。在另外两台计算机上,它可以正常工作(win 7和XP),但在特定计算机上则不能。
问题内容: 所有, 我的类路径已设置为以下文件夹: 我所有的Java文件和类文件都在中列出的文件夹下。 但是在运行in 文件夹时出现以下错误: 谁能帮我理解这里的原因? 问题答案: 您在包装内。您应该坐在包根目录中。上一个文件夹。 然后使用重新执行它。 就是说,您不应该使用环境变量。您的当前也是无效的。未加引号的路径名中有空格。另外,该文件夹不应放在类路径中。只需使用like这样的参数(坐在包根文
