新下载的Android Studio 3.0 Canary 8的问题

Question

我应该在build.gradle或包装器文件中编辑什么来解决这个问题？

我的build.gradle文件

build.gradle

我的gradle-wrapper.properties文件 -

var deleteInvoice = () => {
  return invoiceRecord.remove().then(data => {
    if (data.result.n === 0) {
      // ATTN: it's better to throw Error instances
      throw { code:"INVOICE_NOTFOUND", err:"This invoice could not be found: " + invoiceRecord._id };
    }
  }, err => {
    err.message = 'deleteInvoice ERROR : ' + err.message;
    // Re-throw error
    throw err;
  })
})};
