私はProguardをアンドロイドライブラリで使用していますが、サンプルコードを縮小または難読化しながら特定のクラスにVerifyErrorを作成しているようです。 （つまり、-dontobfuscateと-dontshrinkを使用するとエラーが削除されます）。Proguardを使用した論理演算のVerifyError
私は （コマンド./gradlew clean testがエラーを再現する必要があります）簡単な例でGitHub repository上のエラーを特定できたが、私は本当にここに本当の問題を理解していません。
私の失敗テストが唯一のオブジェクトをインスタンス化しようとします：
package a.b.c;
public class FailingTest {
@org.junit.Test
public void name() throws Exception {
new D();
}
}
と、関連するクラスはそれと同じくらい簡単です：実際に
package a.b.c;
public class D {
public void f(int g) {
if (g < 0) {
System.out.println("test");
}
}
}
任意の論理演算は、エラーを引き起こすだろう（たとえば、メソッド本体にSystem.out.println(g == 2);を入れるだけでも失敗します）。
ProGuardのは、以下のように構成されている：
