有人可以帮助我解决该错误或什么原因导致此错误吗？

Edit1：项目的Gradle文件。错误日志还附带上面的问题。请检查它。

我认为Java编译器和Java sdk如果存在问题，请告诉我这是否是问题以及如何解决。

确保在项目gradle构建脚本中使用：

from numpy import mod

class Particle(object):
    def __init__(self):
        self.idx = 3        # particle id
        self.t = 0.7        # s
        self.mass = 20.     # kg
        self.x = 20.        # m
        self.y = 30.        # m
        self.dt2store = 0.7 # s (simulated time)

    def store(self):
        if mod(self.t, self.dt2store):
            self.writer()

    def writer(self):
        '''
        It stores data in particle id3 file
        data2store = [self.t, self.mass, self.x, self.y]
        '''

还要尝试更新您的库的版本，例如：

classpath 'com.android.tools.build:gradle:3.3.2'
classpath 'com.google.gms:google-services:4.2.0'

使用--stacktrace或--info或--debug运行它以查看来自终端的更多日志输出信息，例如：./gradlew compileDebugJavaWithJavac --debug。

您将能够看到有关何时何地停止任务以及失败原因的更多信息。

答案 2 :(得分：0)

'com.google.firebase:firebase-core:16.0.8'库存在问题，当我从app / gradle中删除它时，它为我解决了问题。

答案 3 :(得分：0)

尝试更新最新版本：

  1. RxJava ：io.reactivex.rxjava2:rxjava
  2. RxAndroid ：io.reactivex.rxjava2:rxandroid

然后，AndroidStudio->文件->使Cashes / Restart无效。

它帮助了我。

答案 4 :(得分：0)

在我的情况下，Publisher类属于我的项目中缺少的RxJava库，因此在我的app / gradle文件中添加以下两行可解决问题：

实现'io.reactivex.rxjava2：rxandroid：2.1.1'

实现'io.reactivex.rxjava2：rxjava：2.x.x'
