如何在 Netbeans 的清单类路径中包含 lib 文件夹

2022-01-20 00:00:00 ide netbeans java classpath manifest.mf

我的 java 应用程序使用的库需要在类路径中查找文件 (log4j.xml).我使用 netbeans 来管理我的项目，但我找不到包含 lib/文件夹的方法.

A library that my java application uses needs looks for a file (log4j.xml) in the class path. I use netbeans to manage my project, but I can't find a way to include the lib/ folder.

Netbeans 自动在应用程序 jar 中创建一个 MANIFEST.MF 文件，并创建一个名为 lib/的文件夹，其中包含所有依赖项.此清单指定了覆盖命令行上提供的任何 -cp 参数的 Class-Path 属性.我可以在 netbeans 的库面板中选择任意文件夹，但它会在清单的类路径中创建一个子文件夹.我想要 lib/文件夹中的所有依赖项和 log4j.xml 文件.

Netbeans automatically creates a MANIFEST.MF file inside the application jar and also creates a folder called lib/ which includes all dependencies. This manifest specifies a Class-Path attribute that overrides any -cp argument provided on the command line. I can select an arbitrary folder in netbeans' library panel, but it creates a sub folder in the manifest's classpath. I'd like all dependencies and the log4j.xml file inside the lib/ folder.

希望可以在 IDE 中执行此操作.我包含了一个自动生成的 build-impl.xml 文件的片段.

Hopefully it's possible to do this in the IDE. I include a snippet of the auto-generated build-impl.xml file.

<target depends="init,compile,-pre-pre-jar,-pre-jar" if="manifest.available+main.class+mkdist.available" name="-do-jar-with-libraries">
    <property location="${build.classes.dir}" name="build.classes.dir.resolved"/>
    <pathconvert property="run.classpath.without.build.classes.dir">
        <path path="${run.classpath}"/>
        <map from="${build.classes.dir.resolved}" to=""/>
    </pathconvert>
    <pathconvert pathsep=" " property="jar.classpath">
        <path path="${run.classpath.without.build.classes.dir}"/>
        <chainedmapper>
            <flattenmapper/>
            <globmapper from="*" to="lib/*"/>
        </chainedmapper>
    </pathconvert>
    <taskdef classname="org.netbeans.modules.java.j2seproject.copylibstask.CopyLibs" classpath="${libs.CopyLibs.classpath}" name="copylibs"/>
    <copylibs compress="${jar.compress}" jarfile="${dist.jar}" manifest="${manifest.file}" runtimeclasspath="${run.classpath.without.build.classes.dir}">
        <fileset dir="${build.classes.dir}"/>
        <manifest>
            <attribute name="Main-Class" value="${main.class}"/>
            <attribute name="Class-Path" value="${jar.classpath}"/>
        </manifest>
    </copylibs>
    <echo>To run this application from the command line without Ant, try:</echo>
    <property location="${dist.jar}" name="dist.jar.resolved"/>
    <echo>java -jar "${dist.jar.resolved}"</echo>
</target>

谢谢.

推荐答案

我找到了一种修改 build-impl.xml 的方法.

I found a way to acheive this modifying the build-impl.xml.

我变了:

<attribute name="Class-Path" value="${jar.classpath}"/>

到:

<attribute name="Class-Path" value="${jar.classpath} /lib"/>

问题是netbeans会覆盖它，因为这个文件是自动生成的.

The problem is that netbeans will overwrite it since this file is automatically generated.
