解決mvn打包報There are test failures.的問題

報錯內容

我的spring-boot項目，使用mvn啓動時是OK的，但是用mvn打包時失敗。報錯：
[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 13.047 s <<< FAILURE! - in com.amwalle.walle.WalleApplicationTests
[ERROR] contextLoads(com.amwalle.walle.WalleApplicationTests) Time elapsed: 0.216 s <<< ERROR!
java.lang.NoSuchMethodError: 'org.springframework.core.annotation.AnnotationAttributes org.springframework.core.annotation.AnnotatedElementUtils.getAnnotationAttributes(java.lang.reflect.AnnotatedElement, java.lang.String)'

詳細報錯內容如下：

解決辦法（1）

跳過打包時的測試出錯

方法一

在執行打包命令時加入參數：-Dmaven.test.failure.ignore=true

mvn package -Dmaven.test.failure.ignore=true

參考鏈接

Maven has its own arguments to deal with this issue:
-Dmaven.test.failure.ignore=true ignores any failure that occurs during test execution
-Dmaven.test.skip=true would not compile the tests
-fn, -fae never fails the build regardless of test results

方法二

在項目的pom.xml文件中加入如下配置：

<build>
  <plugins>
     <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
        <testFailureIgnore>true</testFailureIgnore> </configuration>
    </plugin>
 </plugins>
</build>

解決辦法（2）

出現如上報錯，在我的項目中，根因是我應用的spring frame work包版本衝突。所以需要將衝突的包版本改爲一致。如果有類似問題的，那麼就需要仔細檢查spring相關包版本，看是否有版本不一致的包。如果有將其改爲一致版本

可以看到，我的項目中，spring-tx 的版本是 4.1.6.RELEASE，但是其他包的版本都是 5.0.9.RELEASE。於是我在pom.xml文件中，將spring-tx的版本也修改爲 5.0.9.RELEASE，從而解決了該問題。
