我正在尝试使用 Eclipse 的 maven 插件从 vaadin 7.0.0 打包示例应用程序,但是每次运行目标“包”时,构建都会失败并出现以下错误:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project essai: Execution default-compile of goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile failed: A required class was missing while executing org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile: org/codehaus/plexus/compiler/util/scan/InclusionScanException

mvn package -X 的结果在这里: http: //pastebin.com/jk5uW8Ut

我的 pom.xml 如下: http://maven.apache.org/maven-v4_0_0.xsd"> 4.0.0 com.mycompany essai war 0.0.1-SNAPSHOT Vaadin Web Application

我是 maven 新手,即使我发现很多关于此错误的帖子,我也无法理解可能导致此错误的原因。

这里似乎是问题:

[致命] 不可解析的 POM C:\Users\Benoit.m2\repository\org\apache\maven\maven-parent\16\maven-parent-16.pom

由于这个错误,maven 无法将所有必要的库添加到插件的类路径中。

我建议您删除下的所有内容C:\Users\Benoit\.m2\repository\org\apache\maven\并重建项目。这应该会有所帮助。
