解决mvn打包报There are test failures.的问题
报错内容
我的spring-boot项目，使用mvn启动时是OK的，但是用mvn打包时失败。报错：
[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)'
详细报错内容如下：

解决办法（1）
跳过打包时的测试出错
方法一
在执行打包命令时加入参数：-Dmaven.test.failure.ignore=true
mvn package -Dmaven.test.failure.ignore=true
参考链接
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
在项目的pom.xml文件中加入如下配置：
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.pluginsgroupId>
<artifactId>maven-surefire-pluginartifactId>
<configuration>
<testFailureIgnore>truetestFailureIgnore> configuration>
plugin>
plugins>
build>
解决办法（2）
出现如上报错，在我的项目中，根因是我应用的spring frame work包版本冲突。所以需要将冲突的包版本改为一致。如果有类似问题的，那么就需要仔细检查spring相关包版本，看是否有版本不一致的包。如果有将其改为一致版本
可以看到，我的项目中，spring-tx 的版本是 4.1.6.RELEASE，但是其他包的版本都是 5.0.9.RELEASE。于是我在pom.xml文件中，将spring-tx的版本也修改为 5.0.9.RELEASE，从而解决了该问题。
