apache maven 构建失败 - 无法执行目标 org.apache.felix:maven-bundle-plugin:4.2.0:manifest

Question

我想通过以下位置的文章安装“iText RUPS”

https://github.com/itext/i7j-rups

在命令提示符中输入：“mvn clean package”后我得到：

[INFO] --- maven-bundle-plugin:4.2.0:manifest (bundle-manifest) @itext-rups ---

[ERROR] 发生内部错误 java.util.ConcurrentModificationException

我该如何解决这个问题？

Answer 1

基于：https://github.com/FasterXML/oss-parent/issues/27

您需要更新版本的 maven bundle 插件。

尝试将其添加到 POM 文件的插件部分：

<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>5.1.1</version>
</plugin>

Answer 2

在 Windows 10 上构建 RUPS 时遇到了同样的问题。使用 Java SDK 16.0.1、Apache Maven 3.8.1。我使用了 Archi 为 maven-bundle-plugin 建议的插件 POM 代码。但也最终将插件 launch4j（也在 POM 文件中）从 1.7.25 更新到 2.1.1。这成功地创建了 RUPS jar。 （即使是盲松鼠也会偶尔发现一颗坚果。）
