Flutter：當我嘗試運行從 github 克隆的 flutter 應用程序時，但構建失敗，有人可以告訴我如何解決嗎？

Question

warning: [options] source value 7 is obsolete and will be removed in a future release
warning: [options] target value 7 is obsolete and will be removed in a future release
warning: [options] To suppress warnings about obsolete options, use -Xlint:-options.
error: warnings found and -Werror specified

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':connectivity:compileDebugJavaWithJavac'.
> Compilation failed; see the compiler error output for details.

Answer 1

該錯誤消息意味着，您的 java 代碼有警告。 並且由於-Werror標志，它變成了一個錯誤。

警告說，您的 java 目標版本太舊。

因此，您可以升級該版本。 或者，刪除-Werror 。
