Maven的第谷说龙目岛所需的神器缺少虽然其他依赖工作

我创建了一个P2回购补充一点，我后来成为第谷的依赖使用插件。然而我偶然发现了lombok依赖的错误堆栈。我知道龙目岛有点特别的依赖。所以我下载它并将其添加到我的插件文件夹并安装它。我得到一个不同的错误比我根本就没有在plugins文件夹中的文件夹lombok.jar但在错误堆栈中所列的建议，并没有解决问题。我也试过在这个计算器等岗位Maven的第谷说龙目岛所需的神器缺少虽然其他依赖工作

mvn package fails with Required Artifact Missing even though it exists in my Remote Repository

讨论解决方案，但我仍然有同样的错误。我的groovy依赖添加没有问题。

的URL'HTTP：// projectlombok.org/mavenrepo'似乎是，尽管它的名字没有Maven仓库... – khmarbaise

确定我会尝试找出正确的网址 – kloklo90

龙目岛不同的行为有点作为一个依赖。有两种方法可以让你的lombok相关代码工作。

您可以添加龙目岛作为一个依赖，如下图所示，然后用MVN安装到让它每次你做一个干净的MVN按时上班。另外，您可以打的Maven - >更新项目...发现，如果你右击每次你做一个干净的MVN时间在Eclipse项目。它应该让Lombok重新加载回来。

<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok-maven --> 
<dependency> 
<groupId>org.projectlombok</groupId> 
<artifactId>lombok-maven</artifactId> 
<version>1.16.8.0</version> 
</dependency>

我发现这一切cubbersome的，所以我看着这并不需要右键点击或每MVN干净后MVN安装的替代解决方案。我用delombok一个强大的工具来龙目岛代码转换为东西你的Maven第谷的编译器可以消化。 http://awhitford.github.io/lombok.maven/lombok-maven-plugin/delombok-mojo.html。只需将其添加到您的pom中，并将源文件夹的名称更改为src/main/lombok。当运行时，它会创建/更新的src/main/java文件夹与所有在它delomboked代码不要担心。所以Maven仍将使用src/main/java作为源文件夹来编译所有代码。
