：org.apache.mavenが。 plugin.MojoFailureException：テストに失敗しました。私はMavenの3.3.9使用しますが、私はちょうど「MVN -DskipTests」を使用することはできません、それが原因で、ライフサイクル・フェーズや目標を欠いていると失敗します

Answer 1

。ここにエラーメッセージが表示されます：

ユニットテストの失敗を無視するには、2つの方法があります。例えば相をインストール使用：

method 1: mvn -DskipTests install 

method 2: mvn -Dmaven.test.skip=true install 

2つの方法の間の違いは、前者は、ユニットテストをコンパイルし、後者ではないということであるので、後者は前者ができず、失敗をコンパイルスキップすることができます。
