hdf5在maven项目中 [英] hdf5 in maven project

问题描述

我正在尝试将hdf.hdf5lib.H5导入到NetBeans中的maven项目中。它有这个作为导入行

I'm trying to import hdf.hdf5lib.H5 into my maven project in NetBeans. It has this as import line

import hdf.hdf5lib.H5;

如下所示： https://support.hdfgroup.org/products/java/JNI3/jhi5/index.html

然而，它抛出了这个异常：

However, it throws this exception:

java.lang.ExceptionInInitializerError
Caused by: java.lang.RuntimeException: Uncompilable source code - package hdf.hdf5lib does not exist

NetBeans已警告过我关于它，在进口线说packadge不要激动。所以我让它搜索Maven存储库中的依赖项。它确实找到了一些内容并将其添加到我的pom.xml中：

NetBeans already warned me about it by saying at the import line "packadge does not excist". So I let it "search dependencies at Maven repositories". It does find something and it adds this to my pom.xml:

<dependency>
    <groupId>org.hdfgroup</groupId>
    <artifactId>hdf-java</artifactId>
    <version>2.6.1</version>
    <type>jar</type>
</dependency>

不幸的是，它会在导入行packadge不会激活和错误异常时发出警告。似乎pom.xml的这个补充什么也没做。

Unfortunately it keeps the warning at the import line "packadge does not excist" and the error exception. It seems this addition to the pom.xml does nothing.

我是所有这些的初学者，所以也许解决方案很明显，但我找不到它。这些问题可以追溯到2012年至2014年，但对我没有帮助：

I am a beginner in all of this, so maybe the solution is obvious, but I cannot find it. These questions already date back to between 2012 and 2014, but didn't help me:

添加hdf5库（java） & c ++）到公共maven存储库？

如何在带有NetBeans的Windows Java项目中使用HDF5

hdf5 Java库入门

根据ddarellis的建议，这可能是版本问题。似乎有两种选择。

As suggested by ddarellis this might be a version problem. It seems there are two options.

• HDF Java 3.3.2和HDF5-1.8.19（HDFView版本2.14）


• Java HDF对象包3.0.0和HDF5-1.10

我会尝试两者，但maven建议使用HDF Java 2.6.1是错误的。

I'll try both, but the suggestion from maven to use HDF Java 2.6.1 is wrong.

这篇文章有助于将jarhdf5-3.3.2.jar添加到依赖项中。

This post was helpfull for adding jarhdf5-3.3.2.jar to the dependencies.

https://forums.netbeans.org/post-62903.html#62903

1. 在Maven项目中打开添加依赖关系对话框


2. 组成一些groupId ，artifactId和版本并填充它们，好的。


3. 依赖关系将被添加到pom.xml，并将显示在maven项目的Libraries节点下


4. 右键单击Lib节点并手动安装工件，填充jar的路径Jar应安装到本地Maven仓库，并在步骤2中输入坐标。）

1. In Maven project open "Add dependency" dialog
2. Make up some groupId, artifactId and version and fill them, OK.
3. Dependency will be added to the pom.xml and will appear under "Libraries" node of maven project
4. Right-click Lib node and "manually install artifact", fill the path to the jar Jar should be installed to local Maven repo with coordinates entered in step 2).

好的，所以我安装了HDF5 1.8.19 HDFView2.14并将jarhdf5-3.3.2添加到依赖项中。但是当我尝试运行时出现此错误：

Ok, so I installed HDF5 1.8.19 HDFView2.14 and added jarhdf5-3.3.2 to the dependencies. However I get this error when I try to run:

Caused by: java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
at hdf.hdf5lib.H5.<clinit>(H5.java:230)

推荐答案

链接你参考包含过时的示例，您应该使用这些示例相反。

The link you refer to contains out-of-date examples, you should use these examples instead.

正如 ddarellis 所指出的，正确的包装是：

As pointed by ddarellis, the correct package is:

ncsa.hdf.hdf5lib

以下是打开HDF5文件的工作示例：

Here is a working example of opening an HDF5 file:

import ncsa.hdf.hdf5lib.H5;
import ncsa.hdf.hdf5lib.HDF5Constants;
import ncsa.hdf.hdf5lib.exceptions.HDF5Exception;

public class Foo {

  public void openHdf5File() {
    int flags = HDF5Constants.H5P_DEFAULT;
    int access = HDF5Constants.H5F_ACC_RDWR;

    try {
      int file_id = H5.H5Fopen("myFile.hdf", flags, access);
    } catch (HDF5Exception ex) {
      System.err.println("Failed to open HDF5 file");
    }
  }

}

maven您拥有的依赖关系是正确的，并且是 maven central 上的最新版本。

The maven dependency you have is correct and is the latest available on maven central.
