JDK 11への移行後のSpring BootテストでのMockitoエラー

Question

最新のJava LTSバージョンを使用するために、JDK 11に移行しました。テストでは、次の例外スタックトレースを取得します。

Jdk-10に切り替えると、すべてが正常に機能することに注意してください。私はSpring Bootを使用し、私のテストもMockitoを使用しています。私のpom.xmlもここに示されています。

Spring Bootおよび/またはMockitoとjdk-11の間に既知の非互換性はありますか？おそらく、pom.xmlに別の参照がありませんか？

Answer 1

同じ問題でした。 Mockito 2.22.0を依存関係に追加します。すべてが機能しているようです。

compile group: 'org.mockito', name: 'mockito-core', version: '2.22.0'
