我正在尝试设置一个持续的投放管道，并始终提出UnreachableBrowserException。
这是完整的堆栈跟踪：

[launcher] Process exited with error code 1
以下是我的bash脚本中的相关部分：
#Install protractor and webdriver & start webdriver
npm install -g protractor
webdriver-manager update
webdriver-manager start&
#Install and start application
./gradlew assemble
java -jar bignibou-server/build/libs/bignibou-server.jar&
#Run end2end tests
protractor bignibou-client/protractor.conf.js
有人可以帮忙吗？
编辑1 ：来自protractor.conf.js
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['test/e2e/*.spec.e2e.js']
};
if (process.env.SNAP_CI) {
exports.config.chromeDriver = '/usr/local/bin/chromedriver';
}
编辑2 ：来自我的end2end测试：
describe('Signin page', function () {
beforeEach(function(){
browser.get('http://localhost:8080/#/signin');
browser.refresh();
});
it('should allow user to signin', function () {
element(by.model('credentials.username')).sendKeys('balteo@example.fr');
element(by.model('credentials.password')).sendKeys('------');
element(by.id('submit')).click();
expect(element(by.tagName('h2')).getText()).toBe('Dashboard');
});
});
