[英]How to include the lib folder in the manifest classpath in Netbeans
A library that my java application uses needs looks for a file (log4j.xml) in the class path. 我的Java应用程序使用的库需要在类路径中查找文件(log4j.xml)。 I use netbeans to manage my project, but I can't find a way to include the lib/ folder.
我使用netbeans管理我的项目,但是找不到包含lib /文件夹的方法。
Netbeans automatically creates a MANIFEST.MF file inside the application jar and also creates a folder called lib/ which includes all dependencies. Netbeans会在应用程序jar中自动创建一个MANIFEST.MF文件,并还会创建一个名为lib /的文件夹,其中包含所有依赖项。 This manifest specifies a Class-Path attribute that overrides any -cp argument provided on the command line.
该清单指定了Class-Path属性,该属性将覆盖命令行上提供的任何-cp参数。 I can select an arbitrary folder in netbeans' library panel, but it creates a sub folder in the manifest's classpath.
我可以在netbeans的库面板中选择一个任意文件夹,但是它将在清单的类路径中创建一个子文件夹。 I'd like all dependencies and the log4j.xml file inside the lib/ folder.
我想要所有依赖项和lib /文件夹中的log4j.xml文件。
Hopefully it's possible to do this in the IDE. 希望可以在IDE中执行此操作。 I include a snippet of the auto-generated build-impl.xml file.
我包含了自动生成的build-impl.xml文件的一个片段。
<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>
Thanks. 谢谢。
Instead of editing the build-impl.xml file you should add this entry to the build.xml file. 代替编辑build-impl.xml文件,您应该将此条目添加到build.xml文件中。 When you modify anything in your project pertaining to the building of that project, it will generate a new build-impl.xml file.
当您在项目中修改与该项目的构建有关的任何内容时,它将生成一个新的build-impl.xml文件。
Here is an example of what I put in my build.xml file: 这是我放入build.xml文件的示例:
<target depends="init" name="-do-clean">
<delete dir="${build.dir}"/>
<delete file="${dist.jar}"/>
<delete dir="${dist.dir}/lib"/>
<delete dir="${dist.dir}/resources"/>
</target>
Since I put this in the build.xml file, it will override the "-do-clean" section of the build-impl.xml file which contains: 由于我将其放入build.xml文件中,因此它将覆盖build-impl.xml文件的“ -do-clean”部分,该部分包含:
<target depends="init" name="-do-clean">
<delete dir="${build.dir}"/>
<delete dir="${dist.dir}" followsymlinks="false" includeemptydirs="true"/>
</target>
Furthermore, since it is in the build.xml it won't be modified by Netbeans. 此外,由于它位于build.xml中,因此Netbeans不会对其进行修改。
您只需关闭项目选项Build / Packaging / Copy Dependent Library,然后在项目的根文件夹(这是jar文件中的清单模板)中手动编辑manifest.mf。
I found a way to acheive this modifying the build-impl.xml. 我找到了一种修改build-impl.xml的方法。
I changed: 我变了:
<attribute name="Class-Path" value="${jar.classpath}"/>
to: 至:
<attribute name="Class-Path" value="${jar.classpath} /lib"/>
The problem is that netbeans will overwrite it since this file is automatically generated. 问题在于,由于该文件是自动生成的,因此netbeans将覆盖它。
看来您的问题是将log4j.xml文件存储在/ lib中的“ globmapper”-您希望将其存储在“ /”或jar上。
