java - JMockit 错误 - 附加 API 的 native 库在此 JRE 中不可用

Question

我一直在寻找这个问题的答案，并尝试了我能找到的唯一解决方案 (jmockit: Native library for Attach API not available in this JRE error)

我尝试将 attach.dll 添加到 PATH 环境变量，但没有成功。 (C:\Program Files\Java\jdk1.7.0_60\jre\bin\attach.dll)

还有其他建议吗？

您正在使用 jre 而不是 jdk。转到 Windows->Preferences->Java->Installed JRE's 并删除 jre 并添加 jdk，同时选择它作为默认值。
