無效的CEN標頭（錯誤的簽名）

Question

我在Java方面的工作還不是很多，但是我正在嘗試升級libabry。 我正在嘗試使用Maven在本地運行java google app引擎項目，並且收到錯誤/警告消息（如下所示）。

Java版本：jdk1.8.0_172 Maven版本：3.5.3 appengine.target.version：1.9.63 maven-compiler-plugin：3.7.0（源和目標：1.8）javax.servlet-api：4.0.1

我試圖刪除.m2文件夾並進行mvn全新安裝

任何幫助表示贊賞！ 謝謝。

Answer 1

謝謝大家的幫助！ JAR文件在源代碼上很好。 我對我收到未簽名消息的源文件運行了jarsigner verify 。 在目標文件夾中的JAR文件上運行相同的命令時，出現“無效的CEN標頭（錯誤的簽名）”。 然后我搜索了在mvn構建期間損壞的JAR文件，然后找到了解決方案 。 在mvn生成過程中文件已損壞。 我從pom.xml文件中刪除了<filtering>true</filtering> ，並且停止收到錯誤消息。
