./gradlew桌面：運行不起作用，但設置配置確實：libgdx

Question

當我運行./gradlew desktop:run在Android Studio終端中運行它無法運行。 但是當我設置一個運行配置（Gradle項目是Gradle項目是我的項目並運行任務是“desktop：run”）時，它運行得非常好。 （另外./gradlew android:run也不起作用，它只在我運行自動創建的android配置時才有效。）

./gradlew desktop:run ：

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '10.0.2'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

./gradlew android:run ：

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '10.0.2'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

編輯：網上的一些頁面建議我使用較舊的Java版本，但這不起作用。

您可能在Gradle Wrapper中使用的Gradle版本太舊而無法識別JDK 10.當您直接在Android Studio中運行時，它可能正在使用自己的Gradle版本（我認為導入項目時有一個設置可確定Android Studio是否會使用包裝的Gradle。）

因此，您可以降級JDK或升級Gradle包裝器版本。 降級JDK很痛苦，因為他們已經開始從Sun下載站點刪除舊版本。 你可能有一些非LibGDX的東西，你想用更新的JDK。

要升級Gradle包裝器，請打開/gradle/wrapper/gradle-wrapper.properties並將結尾處的文件名更改為gradle-5.1.1-bin.zip 。 至少，這就是我使用的，它適用於JDK 12。

然后，你需要更換compile關鍵字在你build.gradle與文件implementation 。 在/desktop/build.gradle ，將from files(sourceSets.main.output.classesDir)行from files(sourceSets.main.output.classesDir)更改from files(sourceSets.main.output.classesDirs) （在末尾添加s）。
