Maven：构建失败

时间：2017-11-26 22:40:31

标签： java maven compiler-errors

我花了3天时间寻找这些错误背后的原因，我需要使用特定的框架EclipseLink将这3个表实体映射到PostgreSQL，当然这三个实体之间存在关系：

组 

t = 0
duration = 10
num_strings = 5
while t < 10:
    print(round((t*num_strings/duration)%1, 3))
    t += .1

1 个答案:

答案 0 :(得分：3)

javax.persistence:persistence-api:1.0.2来自24-Jul-2007。

我使用21-Aug-2017中的javax.persistence:javax.persistence-api:2.2代替。

顺便说一句，你为什么要在POM中两次声明maven-compiler-plugin？这导致了警告：

  

[WARNING] 'build.plugins.plugin.(groupId:artifactId)' must be unique but found duplicate declaration of plugin org.apache.maven.plugins:maven-compiler-plugin @ line 27, column 15

这也不好：

  

[WARNING] Using platform encoding (Cp1252 actually) to copy filtered resources, i.e. build is platform dependent!

我在IDE中将编码更改为UTF-8并使用POM properties：

  <properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
  </properties>

这样您就可以完全放弃这些maven-compiler-plugin声明，因为默认情况下compiler:compile和site:site都使用了所有这些属性。
