Kotlin データ クラスがあります。
data class InterviewCreation(
val candidateId: String,
val offerId: String,
val startingDateTime: Long,
val duration: Long,
val location: String,
val description: String?
)
そして、次のように始まる Mapper クラス (Java の場合):
public InterviewCreationViewModel toViewModel(InterviewCreation newInterview, String candidateName, String candidatePhotoUrl) {
String description = newInterview.getDescription();
String location = newInterview.getLocation();
long duration = newInterview.getDuration();
...
}
Lint を実行すると、Mapper クラスでクラッシュする
ECJ compiler crashed processing .../InterviewCreationViewModelMapper.java

そして、多くの誤検知を含む lint レポートを生成します (例外の直後に機能していないだけだと思います)。
私はいくつかのことを試しました：
- データクラスの代わりにクラスを使用
- すべてを最新バージョンにアップグレードする (ツール、SDK など)
- 関連オブジェクトの名前の変更
- Kotlin クラスを Java クラスに置き換えます (この場合は機能します)。
- マッパーを別のクラスの内部クラスにする (このケースは機能します)
- 別のパッケージに移動する
- すべてのメソッドにコメントを付けて、null を返すようにします (これは機能します)。基本的に、最初の 3 行がクラッシュの原因です
- すべての newInterview.get を定数値に置き換えますが、クラッシュもします
明らかに、これらの解決策はどれも望ましいものではありませんが、この時点で私は非常に絶望的です. 私の 2 つの主なオプションは、Lint または Kotlin の使用を停止することです。
どんな提案でも大歓迎です。
