当我在 Angular 项目中运行 mvn install 时，在执行单元测试时收到以下错误消息和构建失败:

我使用frontend-maven-plugin在版本 1.7.6 中，并将其像这样插入到我的 pom.xml 中。

我做错了什么？
最佳答案
在pom.xml中有这一行，这是错误的:
<goals>
<goal>karma</goal>
</goals>
这是错误的原因:运行“karma start karma.conf.ci.js”。这不能以这种方式完成。在 Angular 5 之前可以这样做，但从 Angular 6 开始就不允许了。
第一个版本的pom很好，但是如果它抛出错误，我建议以这样的方式更改它，从angular.json开始:
"test": {
"builder": "@angular-devkit/build-angular:karma",
"options": {
"main": "src/test.ts",
"polyfills": "src/polyfills.ts",
"tsConfig": "src/tsconfig.spec.json",
"styles": [
"src/styles/styles.scss"
],
"scripts": [],
"assets": [
"src/favicon.ico",
"src/assets"
]
},
"configurations": {
"ci": {
"karmaConfig": "src/karma.conf.ci.js"
},
"local":{
"karmaConfig": "src/karma.conf.js"
}
}
这是 ng test 命令将使用的配置。因此，我们也更新 package.json，这一行: "test": "ng test" 应更改为:
"test:local": "ng test --configuration=local",
"test:ci": "ng test --configuration=ci"
最后是 pom xml:
<execution>
<id>test</id>
<goals>
<goal>npm</goal>
</goals>
<configuration>
<arguments>run test:ci</arguments>
</configuration>
</execution>
