"Unable to parse rubocopy response" 将自定义 java 程序加载到 jruby 时 Intellij 出错

Question

在 Intellij 中创建了一个 jruby 项目和一个小的 java 模块来构建 "hello world" java 程序，该程序将由 jruby模块。构建 jrubyjava 模块后，我们可以看到 jruby_hello.rb 是 "happy"，jdk - 来自 java.util.TreeSet 和自定义类来自 com.example.[CallMe, ISpeaker] 可访问 jruby_hello.rb 脚本：

但是 - 当运行 jruby 代码出现以下错误：

这是 rubocop 响应：

Error:jruby.jar is /usr/local/opt/jruby/libexec/lib/jruby.jar {"metadata":{"rubocop_version":"0.79.0","ruby_engine":"jruby","ruby_version":"2.5.7","ruby_patchlevel":"0","ruby_platform":"java"},"files":[{"path":"jruby_hello.rb","offenses":[{"severity":"convention","message":"Missing magic comment # frozen_string_literal: true.","cop_name":"Style/FrozenStringLiteralComment","corrected":false,"correctable":true,"location":{"start_line":1,"start_column":1,"last_line":1,"last_column":1,"length":1,"line":1,"column":1}},{"severity":"convention","message":"Prefer single-quoted strings when you don't need string interpolation or special symbols.","cop_name":"Style/StringLiterals","corrected":false,"correctable":true,"location":{"start_line":1,"start_column":9,"last_line":1,"last_column":14,"length":6,"line":1,"column":9}},{"severity":"convention","message":"Prefer single-quoted strings when you don't need string interpolation or special symbols.","cop_name":"Style/StringLiterals","corrected":false,"correctable":true ...

我们可以注意到隐藏在错误输出中的是

  "message":"Missing magic comment `# frozen_string_literal: true`."

解决这个问题需要什么？

Answer 1

在文件顶部添加该字符串似乎已经解决了问题

# frozen_string_literal: true
require "java"
