问题

我想在Java 10中使用`comb.sun.webkit`包，但是在编译时一直出现错误：

package com.sun.webkit不可见（包com.sun.webkit在模块javafx.web中声明，但未导出）

我尝试通过修改Gradle脚本来修复它：

```gradle
run {
    jvmArgs = ['--add-exports=javafx.web/com.sun.webkit=ALL-UNNAMED']
}

据我所知，我们没有使用模块（项目中没有module-info.java），所以应该可以正常工作。然而，即使指定了jvmArgs，我仍然得到相同的错误。

我做错了什么？

I want to use `comb.sun.webkit` package in Java 10, but I keep getting the error at compilation:

package com.sun.webkit is not visible(package com.sun.webkit is declared in module javafx.web, which does not export it)

I tried to fix it by modifying the gradle script:

```gradle
run {
    jvmArgs = ['--add-exports=javafx.web/com.sun.webkit=ALL-UNNAMED']
}

To my knowledge we are not using modules (no module-info.java in the project) so it should work. Yet, I still get the same error even with the jvmArgs specified.

What am I doing wrong?
