java - 使用 Tycho 项目构建 eclipse 功能时偶尔会出错

Question

我有一个 Maven/Tycho 构建的基于 OSGi 的应用程序，偶尔会因异常而失败。

我有大约 20 个 eclipse 功能，它似乎与实际功能没有任何关系(它可能是每次都失败的不同功能，而且通常构建工作正常)

这不是灾难，但我希望在某个时候修复这个问题，而且我真的不知道如何进一步调试，除非深入研究 Tycho 代码或开始弄乱随机设置。

这会引起任何人的注意吗？

Answer 1

这可能与

有关

• 项目在本地 Maven 存储库和/或远程 Maven 存储库中的可用性
• 您正在执行的构建阶段。

如果包含的 eclipse-plugin 有一个不在任何 Maven 存储库中的版本，并且您只执行构建到不包括安装的生命周期阶段，您可能能够重现该问题。

如果您设法确定问题所在，这将是一个很好的 bug report for Tycho .
