Question

我已经在Android Studio 2.1中启用了Jack，其中包含构建工具版本24 rc3。我开始使用lambda但是当我尝试构建Gradle时抛出此错误：

Execution failed for task ':app:compileDebugJavaWithJack'.
> java.io.IOException: com.android.jack.api.v01.CompilationException: Method 'void <clinit>()' not found in type 'org.dollars_bbs.thedollarscommunity.activities.ChatActivity$ChatFragment$ChatRefresherThread$1$-void_run__LambdaImpl0'

下面：

public class PasswordActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_password);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        View.OnClickListener c = v->{
            TextView t = ((TextView) findViewById(R.id.textView));
            assert t != null;
            if (equal(t.getText().toString(), "xx")) {
                Intent intent = new Intent(getApplicationContext(), MainActivity.class);
                //Clears the Stack so that BACK won't lead here.
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | IntentCompat.FLAG_ACTIVITY_CLEAR_TASK);
                startActivity(intent);

            } else
                Snackbar.make(v, getString(R.string.wrong), Snackbar.LENGTH_LONG).setAction("Action", null).show();
        };

        View b = findViewById(R.id.button);
        if(b != null) b.setOnClickListener(c);
    }

}

我尝试过清洁并重新启动。我不明白为什么会抛出错误，也无法在Google上找到它全栈：

此错误似乎已在Android SDK Build-tools版本24中解决。
