[英]SonarQube. Custom rule needs to access to file
I implemented rule where I needed to extract data from external file. 我在需要从外部文件提取数据的地方实施了规则。 I put this file in resources folder and extract it with the following construction: 我将此文件放在资源文件夹中,并按以下结构进行提取:
CustomRuleCheck.class.getResource(/com/packagename/file.json)
During JUnit testing is everething ok, but when I run an integration testing I cannot get this file. 在进行JUnit测试期间,一切正常,但是当我运行集成测试时,无法获得此文件。
ava.io.FileNotFoundException: file:/home/username/.sonar/cache/587ed81cbc083da501c4bfdcefd65f35/sonar-plugin-0.0.10-SNAPSHOT.jar_unzip/META-INF/lib/custom-checks-0.0.10-SNAPSHOT.jar!/com/packagename/file.json (No such file or directory)
I followed to pointed url and it turned out that folder /home/username/.sonar/cache/587ed81cbc083da501c4bfdcefd65f35/sonar-plugin-0.0.10-SNAPSHOT.jar_unzip/META-INF/lib/
contains custom-checks-0.0.10-SNAPSHOT.jar
and this jar has necessary file inside. 我跟随着指向的URL,结果发现文件夹/home/username/.sonar/cache/587ed81cbc083da501c4bfdcefd65f35/sonar-plugin-0.0.10-SNAPSHOT.jar_unzip/META-INF/lib/
包含custom-checks-0.0.10-SNAPSHOT.jar
,此jar内有必要的文件。 And I don't have any idea how to extract this. 而且我不知道如何提取它。 Could you help me please? 请问你能帮帮我吗?
As I understood,(thanks to @JosefProcházka) sonar-plugin
loads CustomRules in runtime uploading the particular rules from custom-checks.jar
. 据我了解,(感谢@JosefProcházka), sonar-plugin
会在运行时加载CustomRules,并从custom-checks.jar
上传特定规则。 I find a decision how extract resource files from custom-checks.jar
in CustomRules (Custom rules is placed in checks.jar
). 我找到了一个决定如何从custom-checks.jar
中的custom-checks.jar
中提取资源文件(自定义规则放置在checks.jar
)。 I've written down the following util method: 我写下了以下util方法:
public class JarResourcesUtils {
public static File extractFileFromJar(String path) throws IOException {
String resourcePath = JarResourcesUtils.class.getResource(path).getPath();
String jarPath = resourcePath.replace("!" + path, "").replace("file:", "");
try (JarFile jarFile = new JarFile(jarPath)){
Enumeration<JarEntry> entries = jarFile.entries();
while (entries.hasMoreElements()) {
JarEntry entry = entries.nextElement();
String entryName = "/" + entry.getName();
if (entryName.equals(path)) {
InputStream inputStream = jarFile.getInputStream(entry);
File file = File.createTempFile(entryName.replaceAll("//", "_"), ".tmp");
FileUtils.copyToFile(inputStream, file);
return file;
}
}
return null;
}
}
}
Then inside a CustomRules we can get this file: 然后在CustomRules中,我们可以获取以下文件:
File resourceFile = JarResourcesUtils.extractFileFromJar("/com/packagename/file.json");
Of cource, file must be placed in resources directory according to maven conventions 当然,必须根据Maven约定将文件放置在资源目录中
