运行mvn install -P all -e以编译和安装iText后出错。
我之前也做过mvn clean。错误说：
testFlatteningGenerateAppearances2(com.itextpdf.text.pdf.FlatteningTest):
Path to GhostScript is not specified. Please use -DgsExec
我是否需要安装Ghostscript？ 我以为maven会照顾所有的依赖。

答案 0 :(得分：2)
在命令行中添加参数maven.test.skip=true或skipTests=true。测试创建了大量PDF文件（新文档），需要与参考PDF文件（与测试一起存储的现有文档）进行比较。 Ghostscript用于创建这些PDF文件的图像。这些图像以像素为基础进行比较，以检查新文件是否具有相同的参考文件外观。
如果要使用测试构建iText ，则需要Ghostscript。 如果你想仅仅为了获得一个jar来构建iText，你可以跳过测试而不需要Ghostscript。
