Question

我和maven有一个奇怪的问题。我不确定它是什么但似乎在编译我的项目时（使用mvn clean编译）似乎包含了一个错误版本的依赖项。

我想要包含的库是 commons-io 2.4版。当我检查我的IDE时，看起来加载了正确的版本。在我的IDE中编译工作正常。

然而，当我用maven编译项目时，这行代码失败了：

FileUtils.write(new File(propertyService.getStatusPageLocation()), "Some string value");

由于错误：

[ERROR] /C:/projects/my-project/client-externalclient/src/main/java/be/roots/myproject/client/externalclient/jobs/WriteStatusPageJob.java:[60,22] cannot find symbol
[ERROR] symbol:   method write(java.io.File,java.lang.String)

据我所知，该类确实具有该签名的方法。问题似乎只发生在我的电脑上。

有谁知道我还可以尝试调试此问题？

Answer 1

IDE与mvn命令之间可能存在差异的是使用的Java版本。请检查你的路径

Answer 2

检查您的ide中的maven设置。可以在IDE中选择不同的maven路径和自定义settings.xml。

Answer 3

我发现了什么是错的，结果却是一个相当奇特的问题。

对于另一个项目，我安装了高级图像API（http://www.oracle.com/technetwork/java/javase/tech/jai-142803.html），其中包括将额外的.jar文件添加到java sdk中，这些文件将包含在您的核心Java安装中。

在所有libary的.jar文件中，还有较旧版本的commons-io，默认包含在内。

一旦我删除了该库，一切都进展顺利。

Maven似乎使用的是旧版本而不是我期望的版本
