java - 构建 Java derby 项目的 jar 文件时出错

Question

我正在尝试在 netbeans 中构建 java derby 项目的 jar 文件，但遇到此错误。

ant -f C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3 -Dnb.internal.action.name=rebuild clean jar init: deps-clean: Updating property file: C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build\built-clean.properties Deleting directory C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build clean: init: deps-jar: Created dir: C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build Updating property file: C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build\built-jar.properties Created dir: C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build\classes Created dir: C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build\classes\META-INF Copying 1 file to C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build\classes\META-INF Created dir: C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build\empty Created dir: C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build\generated-sources\ap-source-output Compiling 3 source files to C:\Users\Kamal\Documents\NetBeansProjects\JavaApplication3\build\classes warning: Supported source version 'RELEASE_6' from annotation processor 'org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor' less than -source '1.8' Note: Creating non-static metadata factory ...

BUILD FAILED (total time: 2 seconds)

如何解决这个错误？虽然程序运行成功。

Answer 1

可能是因为this Java 中的错误，您可以尝试更改

import static com.sun.xml.internal.fastinfoset.alphabet.BuiltInRestrictedAlphabets.table;

至

import static com.sun.xml.internal.fastinfoset.alphabet.BuiltInRestrictedAlphabets.*;
